If this thought has ever crossed your mind…
I just want you to hear this:

You are not alone, and you are not broken.
So many women have this exact fear — even long before they start trying.
Sometimes it’s quiet, sometimes it’s loud, but it’s real…
and it deserves compassion, not shame.

As a fertility doctor, I see this fear every single day — in women with perfectly healthy cycles, in women who feel disconnected from their bodies, and in women who were never taught how their hormones actually work.

So if you’ve ever wondered, “What if something’s wrong with me?”
I see you.
I’ve been you.
And you deserve support, clarity, and evidence — not fear.

You are allowed to prepare, to learn, to ask questions, and to take care of your future fertility without feeling dramatic or anxious.

This is your reminder:
✨ Your body is adaptable.
✨ Your hormones can be supported.
✨ Your fertility is not defined by a single fear.
✨ And there is so much you can do — starting now.

You’re not alone in this.
And your fertility glow-up is just beginning.

Most of us were never taught what a healthy menstrual cycle actually looks like — and if you’re in your 20s or 30s thinking about pregnancy in 2026, this becomes one of the most important foundations.

And yes… if you feel like you “should already know this,” you are absolutely not alone.
ACOG has published data showing that many women don’t know what a normal cycle length is, how long bleeding should last, or what ovulation actually looks like.
It’s not a personal failure — it’s a systems failure in women’s health education.

So here are the basics, grounded in evidence and what I see every day in practice as a naturopathic endocrinologist:

✨ A normal cycle does NOT mean 28 days.
For most adults, 21- 35 days is physiologically normal.

✨ Your period should last 7 days or less.
Soaking through pads or tampons every 1–2 hours is not normal.

✨ Cycle length can fluctuate.
Small variations are normal — hormones respond to stress, sleep, nutrition, and overall health.

✨ Your luteal phase should be 11-17 days. This is the window that supports implantation.

✨ Your cycle is a monthly hormone report card.
It tells us about thyroid health, iron levels, inflammation, stress hormones, ovulation quality, and metabolic balance.

When you’re preparing for a future pregnancy — especially a 2026 pregnancy — cycle literacy becomes power.

It’s your roadmap.

It’s your insight into why you feel the way you feel.
And it’s one of the most important steps in your fertility glow-up.

Save this for your 2026 fertility prep.
Share it with the friend who never learned this either.
And follow for Episode 4: How to know if you’re actually ovulating.

12/04/2025

If you’re quietly planning for a 2026 pregnancy or if you and your partner just started having those “what if…” conversations this is the fertility foundation I want you to have:

Your labs matter.
And the right labs, at the right time in your cycle, are one of the most important pieces of your fertility glow-up.

Because here’s what the research shows:

Most women have their hormones tested on the wrong days…which means the results don’t actually reflect ovulation or hormone function.

Cycle Day 3–5 is when we run FSH, LH, prolactin, AMH and estradiol.
This tells us about ovarian communication, follicle development, and cycle quality.

Progesterone is not a Day 21 test.
It must be drawn after a positive LH surge, because your body doesn’t follow a calendar, it follows ovulation.

Thyroid antibodies matter (and most women have never had them tested).
Hashimoto’s is linked to irregular cycles, difficulty conceiving, and increased miscarriage risk.

Reverse T3 does NOT improve fertility outcomes.
It’s internet noise, not evidence-based, and not something that guides preconception care.

Iron is one of the biggest missing links.
Low ferritin can delay ovulation, worsen PMS, cause fatigue, and even impact implantation.
Correcting iron stores is one of the most life-changing steps for many women preparing for pregnancy.

Metabolic markers like insulin, fasting glucose, A1c matter more than “hormone trends.”
Blood sugar stability supports ovulation quality, progesterone production, and early embryo development.

These are the labs that move the needle for fertility outcomes.
These are the foundations I run for nearly every woman preparing for pregnancy.
And these are the pieces most women were never taught.

But you deserve clarity.
You deserve data.
And you deserve to feel prepared instead of overwhelmed.

Save this checklist. Share it with your TTC girls. And follow along — Episode 3 is all about what a healthy cycle actually looks like (hint: it’s not just 28 days).

Ask me your lab questions below!

12/03/2025

Think about the first time you brought it up with your partner...
Maybe during a late-night car ride or while brushing youre in together
“What if we try for a baby next year?”
Roadmap unlocked
It’s exciting.
It’s emotional.
And then suddenly your brain starts spiraling:
“Should I already know my cycle better?”
“Is my 31-day cycle normal?”
“What even is the first day of my LMP?”
“Why do I feel behind even though I’m in my twenties or thirties?”
o a fertility
Here’s the truth:
You are NOT behind.
We have research showing that nearly 70% of women in their 20s can’t identify their fertile window.. and over half don’t know what a normal cycle length actually is.
Roadmap unlocked
No one taught you, so how could you know?
And that’s exactly why I created this fertility glow-up roadmap for 2026.
Not a complicated system.
Not fear-based advice.
But the real, evidence-based foundations that support your hormones long before you’re TTC.
Let’s start with foundation #1:
sertility
Know what your cycle is actually telling you.
Here’s your first quick win?
-The first day of youraLiMBp (lastcked menstrual cycle) is the first day of full, red flow - not spotting.
-A normal cycle is anywhere from 24 to 35 days — not just 28.
- Your fertile window about 24 hours and no your OPKs aren’t confirming only predicting ovulation.
Most women were never taught this.
So if you feel confused, behind, or unsure, you are in the majority, not the minority.
I remember that exact feeling when first started thinking about having a baby.
That mix of excitement and “oh my gosh... I have no idea what my body is actually doing.”
I wasn’t the doctor you see today — I was a woman hoping my body would work the way I prayed it would.
Now I have two beautiful little boys. (more on that later). In this series I’m sharing everything | learned along the way...
and everything I wish more women knew before trying that has now made my practice a go-to center for all things fertility care.

This is your fertility glow-up era.
And you’re not doing it alone.

12/01/2025

Think about the first time you finally said it out loud to your partner. maybe in the dark, lying in bed, when everything feels a little more honest and a little less scary:

“What would it look like… if we tried for a baby next year?”

And even as the excitement hits, the worries slip in right behind it.

Because you’ve seen the stories.
Friends who struggled.
Internet posts that made everything sound urgent.
TikTok videos that made you question your hormones.
And suddenly, your brain starts spinning:

— Did I wait too long while I built my career?
— Have I been “healthy,” but not in a fertility-healthy way?
— I’ve been on birth control for years, I don’t even know what my cycle is like.
— What if it doesn’t happen as easily as I hoped?

These thoughts are so normal and also the reason I’m creating this series.

Because you don’t need to panic.
You don’t need to overhaul your life.
And you definitely don’t need the fear-based advice the internet keeps throwing at you.

You need clarity, evidence, and the foundations that genuinely matter for fertility.

So here it is:
26 ways to glow up your fertility in 2026.
The exact habits I teach my patients.
The small shifts that support egg quality, hormones, cycles, and confidence.
The things every woman wishes she knew before trying.

And along the way, you’ll learn more about me too, the doctor who believes in both science and wellness… who’s lived these worries… and who wants this journey to feel empowering, not overwhelming.

If 2026 might be your year, you are in the right place.

Come back for each tip.
Let’s glow up your fertility together. 🌿✨

If you have PCOS, you have to hear this.

If you’ve been told your PCOS could impact your fertility but the advice given was “just keep trying for a year” before getting help… but you have PCOS, that advice doesn’t apply to you. ⛔️

PCOS impacts ovulation, egg quality, and hormone balance — which means you deserve a proactive plan, not a wait-and-see approach.

This is exactly what we do at NMD Wellness — evidence-based, data-driven care personalized for your fertility journey.

If this sounds like you, know that there are options — and we can help you build your fertility strategy, step by step. 💫

You’re doing everything right but… still feel like you’re spinning your wheels.
Because when it comes to fertility, more isn’t always better.
It’s not about another supplement, or another app…
It’s about creating safety, alignment, and evidence-based simplicity for your body to thrive again.

💛 Nothing feels better than taking care of you—the right way. That’s exactly why I’m so passionate about bridging the gap between the best of conventional medicine and the best of natural medicine. You don’t need another “thing” to do, you need a plan.

I’m hosting an on demand mini training all about this and how to maximize your fertility outcomes for REAL. Check out my link in bio or comment “foundation” to get access today!!

Every time I share a patient story like this, someone messages me saying, “That sounds exactly like me!”

This patient had been trying for two years. Every lab was ‘normal, every test fine— but she knew something wasn’t right.
When we finally dug deeper, her progesterone was dropping too soon and her thyroid needed support.
Nothing extreme, just the missing piece.
Three months later... she got her positive test. 💕

This is what happens when we bridge natural and conventional medicine — no guessing, no fluff, just data and compassion working together.

If you’re stuck in that same in-between space — where everything looks normal but nothing feels normal — my free on-demand fertility webinar walks you through exactly how I help patients like her finally get clarity.

From physics labs to fertility labs — life has a funny way of connecting dots ✨

🏈Weekends are my time to recharge

If you have PCOS and feel like getting pregnant is or will be an uphill battle… you’re not alone.

One of my patients, let’s call her Sarah, came to me after months of trying everything she saw online—supplements, diets, endless Google searches. She was exhausted and felt like she was wasting precious time. When we started working 1:1, I helped her cut through all that noise. We focused on evidence-based nutrition, lifestyle shifts, and lab work that actually told us what her body needed. Within a few months, she wasn’t just more confident in her fertility journey—she actually saw her cycles regulate and her chances of conceiving improve.

I know how overwhelming the internet can feel when you’re trying to figure out PCOS and fertility. That’s exactly why I created a free webinar—to give you the clarity you need and focus on what really improves your chances of success.

Spots are limited, so if you’re TTC and want to stop guessing, DM me FOUNDATION for instant access! Let’s make this chapter feel less confusing—and way more hopeful.
