Does this sound like you?

  • The doctors say I’m fine, but I can feel my body is not fine.
  • Everything is going great, except I’m not getting pregnant.
  • I don’t know what to investigate next.
  • I try, I get tired, I give up. And then I try again.
  • I just want to stop worrying about my health and be happy again.

Normal labs don’t always mean optimal. You want to be optimal for fertility and hormone health.

Most check-ups look for disease. I look for why you’re not pregnant yet.

Here’s what you’ve probably heard so far, and what we do instead.

  • What you’ve heard“Just relax and keep trying.”

    What we do instead: We find out why it hasn’t happened yet and work on that.

  • What you’ve heard“Your labs are normal.”

    What we do instead: We compare your results to what’s optimal for fertility, not just the normal range.

  • What you’ve heard“Come back if it hasn’t happened in a year.”

    What we do instead: We start now, so you don’t lose another year waiting.

  • What you’ve heard“It’s genetic. That’s just how you are.”

    What we do instead: We change what you can change: food, sleep, stress, nutrients and daily habits.

  • What you’ve heard“Here’s the pill.”

    What we do instead: We work on what’s causing your symptoms instead of covering them up.

I was told it was genetic. That I’d live with it until pregnancy.

Erika sitting in a rattan chair holding a green juice

Hi, I’m Erika.

For ten years I ended up in the ER with period pain every month. My cycles came every 20 days, or every 90. I had acne, weight that wouldn’t move and no energy after lunch.

Every doctor offered me the pill. I was told it was genetic and that I’d have to live with it until I got pregnant. And for years, I believed them.

Then I stopped guessing and started testing.

I found the root causes of my symptoms. Then I fixed my gut, my blood sugar and my nervous system, one simple step at a time.

Today:

  • I take zero painkillers on my period
  • My cycle is a regular 36 days
  • I’m 20 kg lighter, without crash diets

I went on to do a PhD in developmental and cell biology and trained as a hormone and fertility practitioner. I’m not coaching from theory. I’m giving you the map I had to draw the hard way.

If you’ve been told your labs are normal but you know something isn’t right, I’d love to help.

Five pillars, in the order your body actually needs them.

Most women have been handed pieces of this at random. SEEDS is the sequence that finally fits together.

You looked at everything as a whole! And you actually listened to me and how I was feeling rather than just looking at the numbers and the ranges!

What women often ask me.

Working with me

Who do you work with?

Women with PCOS, irregular or painful periods, endometriosis, low progesterone or unexplained infertility, women trying to conceive after a miscarriage or failed IVF, and women preparing for IVF or IUI. I also work with couples trying to conceive together. Everything is online, with clients all over the world.

How is this different from what my doctor does?

Most check-ups look for disease. I look at why your body isn’t working the way it should yet: your history, cycle, symptoms and labs read against optimal ranges, not just normal ones. I don’t diagnose or prescribe, and I work alongside your doctor, not instead of them.

I’ve tried everything already. Why would this be different?

Most women I work with have tried diets, supplements and advice from the internet. The difference is that we test instead of guess, your plan is built only for you, and we adjust it as your body responds. You can also message me between sessions, so you’re never left alone with a protocol.

Does my partner need to be involved?

It helps, and you’re welcome to come as a couple. Fertility is a shared story, so BeFertile Formula includes guidance on sperm health, and in the Deep Dive your partner gets their own intake form.

Your situation

Is “unexplained infertility” really unexplained?

Often it means the right things simply haven’t been looked at yet. Standard labs are read against ranges built to catch disease, not to support fertility. When we look at optimal values, ovulation quality, thyroid, blood sugar, nutrient levels, gut health and your partner’s sperm health, there are usually gaps worth working on.

Can PCOS be improved naturally?

For many women, yes. PCOS symptoms like irregular cycles, acne and stubborn weight often respond well to targeted work on blood sugar, inflammation, gut health, stress and nutrient levels. I have PCOS myself, and this approach took my cycles from 50 to 90 days down to a regular 36. Every body is different, so your plan is always personal.

Can you help after a miscarriage or failed IVF?

Yes. Many of my clients come to me after a loss or after IVF didn’t work. We look at what may have been missed, from egg quality and hormones to thyroid and inflammation, and prepare your body for the next try, whether that’s natural or with treatment.

Do you work with women and couples going through IVF or IUI?

Yes. I don’t work against your medical treatment. We focus on egg quality, the uterine environment and metabolic health, so your body is in the best possible place for treatment to work.

What is the difference between normal and optimal lab results?

Normal reference ranges are wide because they are designed to flag disease. Optimal ranges are narrower and show where your body tends to work best, especially when you are trying to conceive. That is why you can be told everything looks fine while still dealing with irregular cycles, spotting, PMS or fatigue.

Programs and results

Which option is right for me?

BeFertile Formula is 4 months of 1:1 support, for women who want me by their side until things change. Deep Dive is one 3-hour session ($500) for women who want clear answers and a plan now. BeFertile Space ($15 a month) is ongoing support and community. Not sure? Apply for the free 1:1 call and I’ll tell you honestly.

Why is BeFertile Formula four months long?

An egg takes roughly three months to mature before ovulation, and real changes in your cycle and hormones need a few cycles to show. Four months gives us time to investigate, put your protocol in place step by step and adjust it as your body responds.

How quickly will I see changes?

Most clients notice big changes in their energy, pain and gut issues within the first cycle. Changes in your period, cycle health and lab markers usually follow within a few cycles.

Booking and payment

What happens on the free 1:1 call?

We go over your story so far, look at what might have been missed or needs more support, and talk through your next steps. If working together feels right, I’ll explain how it works. If not, you will still leave with clarity.

Do I need test results before booking?

Not for the free 1:1 call. Just fill out the short booking form when it asks. If you book the Deep Dive directly, it helps to send me all the testing you’ve done so far, so I can review everything before our session.

Do you offer payment plans?

Yes. BeFertile Formula can be split into monthly payments. Deep Dive is a one-time payment.

Can I cancel BeFertile Space any time?

Yes. It’s $15 a month and you can cancel any time.
