Fertility & Trying to Conceive

The most-searched fertility questions โ€” answered with clinical precision and the honest context your doctor doesn't always have time to give you.

Most healthy couples under 35 conceive within 6โ€“12 months. But "healthy" is doing a lot of work in that sentence โ€” and the timeline varies significantly based on age, cycle regularity, and underlying conditions.

  • Under 35: Seek evaluation after 12 months of timed intercourse
  • 35โ€“39: Seek evaluation after 6 months
  • 40+: Pursue evaluation promptly โ€” don't wait
  • PCOS, Hashimoto's, irregular cycles, or prior loss: Don't wait at all. Earlier evaluation protects your timeline.
At NMD Wellness, we never tell patients to "just keep trying." Every month without a plan is a month you can't get back. If something feels off, it's worth investigating now.

A truly comprehensive fertility workup goes well beyond the basic FSH and estradiol most OBs order. Here's what we evaluate at NMD Wellness to build a complete Fertility Blueprint:

Hormone Panel
  • FSH & LH
  • Estradiol (Day 3)
  • Progesterone (Day 21)
  • AMH (ovarian reserve)
  • Prolactin
  • Testosterone (total + free)
  • DHEA-S
Thyroid Panel
  • TSH
  • Free T3 & Free T4
  • TPO antibodies
  • Thyroglobulin antibodies
Metabolic Panel
  • Fasting insulin & glucose
  • HbA1c
  • Lipid panel
  • CRP (inflammation)
  • Vitamin D
Partner Testing
  • Comprehensive semen analysis
  • Sperm DNA fragmentation
  • Hormone panel if indicated
Most patients who come to us have had "normal" labs from their OB โ€” but normal and optimal are not the same thing. We interpret labs in the context of fertility, not just standard reference ranges.

Ovulation is commonly misunderstood โ€” and the tools most women use only tell part of the story.

Signs of ovulation include: egg-white cervical mucus, a positive OPK (LH surge), mittelschmerz (one-sided cramping), and a sustained rise in basal body temperature after ovulation.

What OPKs don't tell you: A positive OPK means your LH has surged โ€” but it does not confirm that an egg was actually released. Women with PCOS frequently have multiple LH surges per cycle without ovulating.

The most reliable confirmation of ovulation is a mid-luteal progesterone test โ€” drawn approximately 7 days after suspected ovulation. A result of โ‰ฅ3 ng/mL confirms ovulation occurred, though an optimal level is 10 ng/mL or above โ€” lower levels may indicate ovulation happened but with a suboptimal luteal phase response.

If you've been relying on OPKs alone and not getting pregnant, a progesterone draw could give you much more useful information โ€” and it's one of the first things we evaluate.

Your fertile window is the 6 days ending on the day you ovulate. Your chances are highest when you have sex 1โ€“2 days before ovulation โ€” this is when sperm are already present and waiting when the egg is released.

For a typical 28-day cycle, this means days 12โ€“14 โ€” but timing varies based on your cycle length. Tracking cervical mucus and basal body temperature alongside OPKs gives you a much clearer picture than cycle day counting alone.

How often should we have sex when trying to conceive?
Every 1โ€“2 days during your fertile window gives you the best odds. If that feels like too much pressure, 2โ€“3 times per week works nearly as well. More frequent sex does not decrease your chances โ€” daily intercourse is perfectly fine and does not reduce sperm quality. What matters far more than frequency is timing.

For women with irregular cycles, PCOS, or unpredictable ovulation, cycle-day guidelines become less reliable. Working with a fertility-focused provider to understand your specific ovulation pattern is the most accurate โ€” and least stressful โ€” approach.

Birth control does not cause infertility โ€” but it can mask underlying hormonal conditions for years. When you stop, those conditions resurface, and women often assume the pill "caused" the problem. It didn't. The problem was already there.

What's common after stopping birth control:

  • Irregular or absent cycles for 3โ€“6 months
  • Delayed ovulation or anovulatory cycles
  • Hormonal acne returning
  • Spotting or unusually long cycles
  • PCOS symptoms emerging for the first time

If your cycles haven't normalized within 3 months of stopping, or if you're actively trying to conceive, a fertility evaluation is appropriate โ€” not something to wait on.

Post-birth control syndrome is real, and addressing it proactively with targeted lab work and a clear protocol dramatically shortens the path to pregnancy for many patients.

More than most couples realize. Male factor contributes to approximately 40โ€“50% of fertility challenges โ€” yet it's often the last thing evaluated.

A comprehensive semen analysis looks at count, motility, morphology, and volume. But sperm DNA fragmentation โ€” which measures the integrity of the genetic material inside sperm โ€” can be normal on a standard analysis and still be the reason conception isn't happening or pregnancies are being lost.

What impacts sperm quality:

  • Heat exposure (laptops, hot tubs, tight clothing)
  • Alcohol, especially frequent or heavy use
  • Poor sleep and high stress
  • Nutrient deficiencies (zinc, CoQ10, folate, vitamin C)
  • Environmental toxin exposure
  • Sedentary lifestyle or overtraining

The good news: sperm regenerate on a 90-day cycle. Targeted lifestyle and supplement changes can meaningfully improve sperm parameters within three months.

At NMD Wellness, we evaluate both partners from the start. Fertility is a team effort โ€” and treating only one half of the equation misses too much.

No. There is no evidence that specific sexual positions โ€” or what you do after sex, like lying down with your legs elevated โ€” affects your chances of getting pregnant. Sperm reach the cervix within seconds of ejaculation regardless of position.

This is one of the most common fertility myths, and it matters because unnecessary post-sex rituals can add anxiety to an already stressful process. Focus your energy on timing, not position.

Several lifestyle factors have meaningful, evidence-based impact on fertility outcomes:

  • Maintain a healthy weight. A BMI between 19โ€“24 is one of the most important fertility factors. For women with obesity and irregular cycles, losing just 5โ€“10% of body weight can significantly improve ovulation rates and live birth rates.
  • Quit smoking. Smoking increases time to conception by 54% and reduces fertility at all levels of use. This includes e-cigarettes.
  • Limit alcohol. Keeping consumption to fewer than 2 drinks per day is associated with better outcomes. Eliminating it entirely during active trying is the safest approach.
  • Avoid recreational drugs. Marijuana and recreational drugs negatively affect both female and male fertility.
  • Reduce caffeine. High caffeine intake has been associated with increased time to conception and miscarriage risk.
  • Minimize environmental toxin exposure. Choose low-pesticide produce when possible, avoid high-mercury fish, and reduce exposure to plastics and chemical products where feasible.
These aren't minor tweaks โ€” they are among the highest-impact changes you can make before starting fertility treatment or while actively trying to conceive. At NMD Wellness, we address all of these as part of a comprehensive fertility plan.

Yes โ€” and the evidence is stronger than most people realize. A "pro-fertility diet" has been directly associated with improved live birth rates in women undergoing fertility treatment. In one study, for every 4-point increase in adherence to this dietary pattern, there was a 53% higher chance of live birth.

What a pro-fertility diet includes:

  • Supplemental folic acid and vitamin B12
  • Optimized vitamin D
  • Fruits and vegetables with low pesticide residue
  • Whole grains
  • Seafood (low-mercury varieties)
  • Dairy and soy

What to reduce or avoid: trans fats, red meat, processed foods, and high-pesticide produce.

What makes this approach effective isn't any single food โ€” it's the cumulative anti-inflammatory, nutrient-dense pattern that supports egg quality, hormone balance, and uterine environment.

Folic acid (at least 400 mcg daily) is essential for all women trying to conceive โ€” this is non-negotiable for neural tube defect prevention. Beyond that, the evidence for specific supplements varies:

  • CoQ10 (Coenzyme Q10): The most promising supplement for egg quality, particularly for women over 35 or with diminished ovarian reserve. Studies show CoQ10 may improve clinical pregnancy rates and increase eggs retrieved during fertility treatment. Typical studied dose: 200โ€“600 mg daily for at least 2 months. Use the ubiquinol form for better absorption.
  • Vitamin D: Women with sufficient vitamin D levels (above 30 ng/mL) have better pregnancy rates. Supplementation at 1,000โ€“4,000 IU daily may improve clinical pregnancy rates in women with deficient or insufficient levels.
  • DHEA: Evidence is mixed. While some studies suggest benefit for poor ovarian responders, the highest-quality research does not show significant improvement in live birth rates. Best used under direct medical supervision.

What about antioxidants in general? Antioxidants may improve clinical pregnancy rates, but evidence for live birth improvement is inconsistent and the research quality is limited. If you choose to take antioxidants, discuss specific types and doses with your provider before adding them.

Most studies showing supplement benefit used them for at least 2โ€“3 months before attempting conception or starting fertility treatment โ€” aligning with the 3-month cycle of egg development. Starting early gives you the most leverage.

CoQ10 supplementation (200โ€“600 mg daily for 2โ€“3 months) has shown the most consistent benefit in improving egg numbers and pregnancy rates for women with diminished ovarian reserve. Maintaining optimal vitamin D levels and following a pro-fertility diet also support egg quality.

It's important to be honest about what the evidence does and doesn't show: age-related decline in egg quality cannot be completely reversed. What we can do is optimize the conditions under which your eggs develop โ€” reducing oxidative stress, improving mitochondrial function, balancing hormones, and supporting the follicular environment.

This is why we start the optimization process as early as possible. The 90 days before an IVF retrieval or a conception attempt are when these interventions have the most impact.

Secondary infertility is the inability to conceive or carry a pregnancy to term after previously having one or more biological children. It is far more common than most people realize โ€” and far more isolating, because it often comes without the acknowledgment that primary infertility receives.

If you've had a child before, you may have been told to "just relax," "it worked before," or "at least you have one." Those words, however well-intentioned, don't address what is almost always a real, identifiable physiological change.

Common causes of secondary infertility include:

  • Age-related decline in egg quality or ovarian reserve โ€” even a few years can make a meaningful difference
  • Changes in hormonal balance, including thyroid disorders that developed or worsened after a previous pregnancy
  • PCOS that was masked during a previous pregnancy or has changed in presentation
  • Postpartum hormonal shifts that never fully resolved
  • Changes in sperm quality in the male partner
  • Uterine changes such as scar tissue, fibroids, or polyps
  • Autoimmune conditions including Hashimoto's
  • Insulin resistance or metabolic changes that developed between pregnancies

Secondary infertility deserves the same thorough evaluation as primary infertility โ€” a comprehensive hormone panel, thyroid workup, ovarian reserve testing, and partner evaluation. The fact that you conceived before does not mean a problem doesn't exist now.

At NMD Wellness, we see a significant number of secondary infertility patients, and we take this experience just as seriously as primary infertility. Your previous pregnancy does not disqualify your struggle โ€” it is part of your history, not an explanation for what's happening now.

PCOS

PCOS is the most common hormonal disorder in women of reproductive age โ€” and one of the most misunderstood. Here's what you actually need to know.

Polycystic Ovary Syndrome (PCOS) is a hormonal condition affecting 1 in 10 women of reproductive age. It is diagnosed using the Rotterdam Criteria โ€” you need at least 2 of the following 3 features:

  • Irregular or absent periods (fewer than 8 per year)
  • Elevated androgens (high testosterone or DHEA-S on labs, or symptoms like acne, excess hair growth, hair thinning)
  • Polycystic ovaries on ultrasound (12+ follicles per ovary)

Despite the name, you do not need to have cysts on your ovaries to have PCOS โ€” and not everyone with PCOS looks the same. There are multiple PCOS subtypes, and the right treatment depends entirely on which type you have.

Many women are told they have PCOS and handed a birth control prescription. That addresses symptoms โ€” it doesn't treat the underlying hormonal pattern. At NMD Wellness, we identify your specific subtype and build a protocol around it.

Yes โ€” and many women do. PCOS is one of the most treatable causes of infertility when approached correctly.

The primary fertility challenge with PCOS is irregular or absent ovulation. When you don't ovulate consistently, there's no egg available to fertilize. But this is addressable.

What drives PCOS-related infertility:

  • Insulin resistance (present in up to 70% of PCOS cases)
  • Elevated androgens (testosterone, DHEA-S)
  • LH/FSH imbalance disrupting follicle development
  • Inflammation
  • Post-birth control hormonal disruption

When we address these root causes โ€” particularly insulin resistance โ€” ovulation often restores naturally, and many patients conceive without medication or IVF.

The key is not just treating PCOS in general, but identifying which mechanisms are driving your specific case. That requires the right labs, the right interpretation, and a plan built around your numbers.

There is no single "PCOS diet" that works for everyone โ€” because PCOS has different root causes in different women. But there are evidence-based dietary principles that benefit most PCOS subtypes, particularly those driven by insulin resistance.

What the research consistently supports:

  • 30โ€“40g of protein at each meal to stabilize blood sugar and reduce cravings
  • Reducing refined carbohydrates and ultra-processed foods
  • Eating carbohydrates alongside fat and protein โ€” never alone
  • Anti-inflammatory foods: fatty fish, olive oil, leafy greens, berries
  • Avoiding blood sugar spikes, especially in the morning

For lean PCOS (without insulin resistance), the approach shifts toward adrenal support, stress reduction, and anti-inflammatory eating rather than carb restriction.

For post-pill PCOS, the focus is on supporting the HPG axis recovery and replenishing nutrients depleted by oral contraceptives.

What works for one PCOS patient can make another worse. Knowing your subtype changes everything about the nutritional approach.

PCOS does not go away after pregnancy โ€” it is a lifelong hormonal condition. However, symptoms can significantly improve or worsen depending on lifestyle factors, weight, and hormonal changes that occur through pregnancy and postpartum.

Many women with PCOS notice their cycles become more regular during the postpartum period, particularly if breastfeeding. Others find that PCOS symptoms return or intensify after their cycle resumes.

Postpartum is also a critical window for women with PCOS to reassess their metabolic health โ€” as pregnancy can accelerate insulin resistance and thyroid dysfunction in susceptible women.

We support PCOS patients through pregnancy, postpartum, and beyond โ€” because managing PCOS is a long-term relationship with your body, not a one-time fix.

Supplement recommendations for PCOS should always be tailored to your specific labs and subtype โ€” not chosen from a general PCOS list. That said, several are well-supported by clinical evidence across most PCOS presentations:

  • Inositol (Myo + D-chiro in a 40:1 ratio): Improves insulin signaling, ovulation, and egg quality. Among the most evidence-backed supplements for PCOS.
  • Magnesium glycinate: Supports insulin sensitivity, sleep, and stress response.
  • Vitamin D: Frequently deficient in PCOS and linked to insulin resistance and ovulatory dysfunction.
  • N-Acetyl Cysteine (NAC): Improves insulin sensitivity and has been shown to support ovulation comparably to Metformin in some studies.
  • Berberine: A powerful insulin sensitizer โ€” often used alongside or instead of Metformin.
  • Omega-3s: Reduce androgen levels and inflammation.
The right supplements depend on which PCOS mechanisms are active in your case. Taking the wrong ones โ€” or the right ones in the wrong doses โ€” can be ineffective or counterproductive. We always base recommendations on your labs.

Thyroid Health & Hashimoto's

Thyroid disorders are among the most underdiagnosed drivers of infertility, weight gain, fatigue, and hormonal imbalance in women โ€” and the standard TSH test alone misses a lot.

Hypothyroidism occurs when the thyroid gland doesn't produce enough thyroid hormone. Because thyroid hormone affects virtually every cell in your body, the symptom list is wide โ€” which is also why it's so often missed or attributed to other causes.

Common hypothyroid symptoms:

  • Persistent fatigue and low energy, even after a full night's sleep
  • Weight gain or difficulty losing weight despite diet and exercise
  • Cold intolerance โ€” feeling cold when others aren't
  • Brain fog, poor memory, difficulty concentrating
  • Hair thinning or loss, including eyebrow thinning (outer third)
  • Dry skin and brittle nails
  • Constipation
  • Depression or low mood
  • Slow heart rate
  • Irregular or heavy periods
  • Difficulty conceiving or recurrent miscarriage
Many women with hypothyroidism are told their TSH is "normal" and dismissed โ€” but a TSH in the upper range of normal (above 2.5) can still suppress fertility and cause symptoms. We interpret thyroid labs in the context of your symptoms and goals, not just the standard reference range.

Hashimoto's is an autoimmune condition in which the immune system mistakenly attacks the thyroid gland. It is the most common cause of hypothyroidism in the United States, and it affects women at a rate approximately 7 times higher than men.

Hashimoto's can be present for years โ€” even decades โ€” before TSH becomes abnormal on a standard test. This is why testing TPO and thyroglobulin antibodies is essential for anyone experiencing thyroid symptoms or struggling with fertility.

How Hashimoto's impacts fertility:

  • Disrupts ovulation and cycle regularity
  • Reduces progesterone in the luteal phase
  • Impairs implantation
  • Significantly increases risk of miscarriage
  • Can contribute to poor egg quality over time

For patients trying to conceive, research supports optimizing TSH to 1.0โ€“2.5 mIU/L โ€” not the standard "under 4.5" used in general practice. Reducing thyroid antibodies through anti-inflammatory protocols also plays a meaningful role in improving outcomes.

Hashimoto's is one of the most common conditions we uncover in patients who have been told "everything looks normal." If you've had recurrent miscarriages or are struggling to conceive without explanation, Hashimoto's testing is essential โ€” not optional.

Most conventional providers only test TSH. While TSH is a useful starting point, it tells you about the pituitary's signal to the thyroid โ€” not about what's actually happening at the cellular level. Here's what each marker tells you:

  • TSH (Thyroid Stimulating Hormone): A pituitary hormone that tells the thyroid to produce more hormone. High TSH = thyroid is struggling. Low TSH = thyroid is overactive. But TSH can be "normal" while T3 and T4 are suboptimal.
  • Free T4: The storage form of thyroid hormone. Needs to be converted to T3 to be used by your cells.
  • Free T3: The active form of thyroid hormone. This is what your body actually uses. Many patients have normal TSH and T4 but low Free T3 โ€” meaning conversion is impaired โ€” and this is completely missed without the full panel.
  • TPO Antibodies: Indicate immune activity against the thyroid. Positive results confirm Hashimoto's even when TSH is still normal.
At NMD Wellness, we never rely on TSH alone. A complete thyroid panel โ€” including Free T3, Free T4, and antibodies โ€” is standard for every patient, because what you can't measure, you can't treat.

Yes โ€” but not by trying harder with the same approach that isn't working. Hypothyroidism slows your metabolic rate, impairs insulin sensitivity, increases fluid retention, and dysregulates hunger hormones. Calorie restriction alone often backfires because it can further suppress thyroid function and cortisol regulation.

What actually moves the needle for weight loss with hypothyroidism:

  • Optimizing thyroid hormone levels โ€” including Free T3, not just TSH
  • Addressing adrenal function and cortisol patterns
  • Prioritizing protein (30โ€“40g per meal) to support metabolism and muscle
  • Stabilizing blood sugar โ€” especially important as insulin resistance frequently co-exists
  • Strength training over chronic cardio
  • Supporting selenium and iodine status for T4-to-T3 conversion
  • Reducing inflammatory foods that drive immune activity
If you're doing "everything right" and still not losing weight, your thyroid โ€” specifically your Free T3 level โ€” deserves a closer look. Treating the root cause changes everything.

Hormones & Menstrual Cycles

Your cycle is a vital sign. Irregular, painful, or absent periods are not something to push through โ€” they're your body communicating something worth listening to.

Irregular cycles โ€” defined as cycles shorter than 21 days, longer than 35 days, or varying significantly month to month โ€” almost always indicate that ovulation is not happening consistently. The most common underlying causes include:

  • PCOS โ€” the leading cause of irregular cycles in women of reproductive age
  • Thyroid dysfunction โ€” both hypo and hyperthyroidism can disrupt cycle length and regularity
  • High stress and elevated cortisol โ€” chronic stress suppresses the HPG axis, the hormonal cascade that drives ovulation
  • Under-eating or excessive exercise โ€” caloric deficit signals to the body that it is not safe to reproduce
  • Post-birth control hormonal disruption โ€” cycles can take 3โ€“6+ months to regulate after stopping hormonal contraception
  • Elevated prolactin โ€” which suppresses ovulation
  • Perimenopause โ€” cycle irregularity is often the first sign
  • Insulin resistance โ€” elevated insulin drives androgen production which disrupts follicle development
Irregular cycles are not a cosmetic inconvenience โ€” they are a diagnostic signal. At NMD Wellness, we treat irregular cycles as the root cause investigation they deserve, not just a reason to prescribe birth control.

Painful periods (dysmenorrhea) are common โ€” but common is not the same as normal. Mild cramping in the first day of your period can be physiologically expected. Debilitating pain that disrupts your daily life, requires strong pain medication, or has worsened over time is not something to simply manage.

Causes of significant period pain include:

  • Endometriosis โ€” tissue similar to the uterine lining growing outside the uterus. Affects 1 in 10 women and is frequently undiagnosed for years.
  • Adenomyosis โ€” endometrial tissue within the uterine muscle wall
  • Uterine fibroids
  • Elevated prostaglandins โ€” driven by inflammation, poor omega-3 to omega-6 balance, and estrogen dominance
  • Progesterone deficiency
  • PCOS

From an integrative standpoint, reducing systemic inflammation, optimizing omega-3 intake, and balancing estrogen and progesterone can significantly reduce period pain โ€” even while a more complex workup is underway.

"I've always had painful periods" is not a complete answer. If pain is your normal, we want to understand why โ€” because there is almost always something addressable underneath it.

Estrogen dominance refers to a state where estrogen is high relative to progesterone โ€” not necessarily because estrogen is too high in absolute terms, but because progesterone is insufficient to balance it.

Symptoms of estrogen dominance:

  • Heavy, painful, or clotty periods
  • PMS โ€” mood swings, bloating, breast tenderness
  • Weight gain, especially around the hips and abdomen
  • Fibrocystic breasts
  • Fibroids
  • Headaches linked to your cycle
  • Anxiety and irritability in the luteal phase
  • Difficulty losing weight

Common drivers of estrogen dominance: insufficient progesterone production, poor liver detoxification of estrogen, high body fat (adipose tissue converts androgens to estrogen), gut dysbiosis (the estrobolome), and environmental estrogen exposure from plastics and personal care products.

Estrogen dominance is one of the most common patterns we see โ€” and it responds beautifully to the right combination of nutritional, lifestyle, and supplemental support when the root cause is properly identified.

IVF & Assisted Reproduction Prep

IVF is a significant physical and financial investment. The 90 days before your cycle are one of the most powerful windows to improve your outcomes โ€” and most fertility clinics don't address it.

Egg quality is one of the most important predictors of IVF success โ€” and while eggs cannot be "created," the environment in which they develop over the 90 days before retrieval can be meaningfully optimized.

Evidence-based strategies to support egg quality:

  • CoQ10 (Ubiquinol form, 400โ€“800mg/day): Supports mitochondrial function inside the egg โ€” the energy engine driving fertilization and early embryo development
  • DHEA (with supervision): Supported by research for women with diminished ovarian reserve โ€” improves response to stimulation and embryo quality
  • Methylated folate: Essential for DNA methylation in the developing egg and embryo
  • Vitamin D optimization: Low Vitamin D is associated with poorer fertilization rates and embryo quality
  • Omega-3 fatty acids: Support follicular fluid quality and reduce inflammation
  • Blood sugar stabilization: Insulin resistance directly impairs egg quality and ovarian response
  • Thyroid optimization: TSH should be under 2.5 before an IVF cycle โ€” preferably closer to 1.0โ€“1.5
  • Reducing oxidative stress: Alcohol, smoking, environmental toxins, and poor sleep all impair mitochondrial function
The 90 days before your retrieval are the most important โ€” because that's when the eggs you'll transfer are developing. Starting earlier gives you the most leverage. We regularly support IVF patients alongside their fertility clinic to maximize outcomes.

Yes โ€” when applied as an integrative layer alongside your fertility clinic, not as a replacement for it. The role of naturopathic endocrinology in IVF prep is to optimize the terrain: your hormones, your thyroid, your metabolic health, your egg environment, and your stress response.

Your fertility clinic is expert in the mechanics of IVF โ€” stimulation protocols, egg retrieval, transfer. What they typically don't address in depth: your thyroid antibodies, your insulin sensitivity, your nutritional status, your sleep quality, or the root cause of any previous failed cycles.

We work in collaboration with your REI โ€” never in competition. The combination of excellent clinical IVF care and targeted integrative preparation is, for many patients, the difference between a failed cycle and a successful one.

Several of our IVF prep patients come to us after failed cycles. The most common finding: something addressable was missed โ€” thyroid antibodies, insulin resistance, a nutrient deficiency, or suboptimal sperm DNA. Earlier is always better, but it's never too late to prepare.

Postpartum Care

The postpartum period is one of the most hormonally turbulent seasons a woman's body will experience โ€” and the standard 6-week checkup is rarely enough.

Because your hormone levels undergo one of the most dramatic shifts the human body experiences โ€” and most of it happens in the days and weeks after delivery, largely without support.

Within hours of delivering the placenta, progesterone and estrogen plummet. Prolactin surges to support breastfeeding. Cortisol is elevated from the stress of labor and sleep deprivation. Thyroid function is particularly vulnerable โ€” postpartum thyroiditis affects up to 10% of women and is frequently missed.

Common postpartum hormonal symptoms:

  • Extreme fatigue beyond normal new-parent sleep deprivation
  • Postpartum hair loss (typically peaks at 3โ€“4 months)
  • Mood changes, anxiety, or depression
  • Brain fog and poor concentration
  • Low libido
  • Difficulty losing pregnancy weight
  • Irregular cycles when they return
  • Joint pain or body aches
These symptoms are not inevitable, and they are not simply "what having a baby does to you." Many are addressable with targeted hormonal support, nutrient repletion, and thyroid evaluation. You deserve more than being told this is normal โ€” you deserve a plan.

Postpartum thyroiditis is an autoimmune inflammation of the thyroid gland that occurs within the first year after delivery. It affects approximately 1 in 10 women โ€” and the majority are never diagnosed because the symptoms overlap so heavily with "normal" postpartum experience.

It typically follows one of two patterns: a temporary hyperthyroid phase (palpitations, anxiety, weight loss) followed by a hypothyroid phase (fatigue, weight gain, depression, brain fog) โ€” or hypothyroidism alone.

Women with Hashimoto's antibodies before pregnancy are at significantly higher risk. But it can also occur in women with no prior thyroid history.

Testing: TSH, Free T3, Free T4, and thyroid antibodies at 6โ€“8 weeks postpartum โ€” and again at 3โ€“6 months if symptoms persist.

Postpartum thyroiditis is one of the most under-diagnosed conditions we see. If you're exhausted, struggling with mood, or experiencing hair loss well beyond the "normal" shedding window โ€” your thyroid deserves evaluation, not reassurance.

Working With NMD Wellness

What to expect, who we see, and how to get started.

Our patients are women who are done with fragmented, reactive care โ€” and ready for something genuinely different. Most come to us because they've been told their labs are "normal" while feeling anything but, or because they've received a diagnosis (PCOS, Hashimoto's, unexplained infertility) without a real treatment plan.

We commonly support women who are:

  • Preparing for pregnancy and wanting to optimize before trying
  • Actively trying to conceive โ€” naturally or alongside IVF/IUI
  • Navigating PCOS, Hashimoto's, or thyroid disease
  • Pregnant and wanting integrative support alongside their OB
  • Postpartum and struggling with hormonal symptoms beyond what their provider is addressing
  • Navigating perimenopause and menopause
  • Experiencing unexplained fatigue, weight changes, or hormonal imbalance

Both. We see patients in person at our Scottsdale, Arizona clinic and offer full concierge telehealth care for patients throughout California. Virtual patients receive the same depth of care โ€” comprehensive lab reviews, personalized protocols, direct messaging access, and ongoing membership support.

If you are outside of Arizona or California, we offer evidence-based online courses and programs designed to support your fertility and hormone journey from anywhere.

Yes โ€” and this is something we prioritize. With your permission, Dr. Zen coordinates directly with your OB, REI, endocrinologist, or other providers. We view ourselves as the integrative layer within a collaborative care team โ€” not a replacement for your existing doctors.

Many of our patients are simultaneously working with a fertility clinic, and we actively support IVF and IUI cycles alongside their REI's protocol. Communication between providers, when welcomed, significantly improves outcomes.

We do not bill insurance directly for membership or visits. As a concierge practice, this allows us to provide the depth, time, and continuity of care that insurance-based models simply don't support. Many patients use HSA or FSA funds for their membership, and we provide superbills you can submit to your insurance for potential reimbursement. Lab orders can typically be run through your existing insurance.

Investment details are discussed personally on your discovery call with Dr. Zen.

The first step is booking a discovery call with Dr. Zen. Before your call, you'll complete a short intake form so Dr. Zen can review your health history and goals in advance โ€” so your conversation is spent on strategy, not background.

On the call, Dr. Zen will listen to your story, answer your questions honestly, and give you her clinical perspective on whether and how she can help. If membership is the right fit, she'll walk you through exactly what care would look like for you. If it isn't, she'll tell you โ€” and point you toward the right resources.

You don't need to have everything figured out before you book. Come with your questions, your history, and your goals. That's exactly what the discovery call is for.
