Get pregnant with clarity & confidence.

Whether you’re trying to conceive naturally, preparing for IVF, or managing a diagnosis like PCOS or endometriosis — there are hidden drivers affecting your fertility that are worth investigating.

I'm Sarah Jane Sandy — a Certified Nutrition Therapist and functional fertility nutritionist specializing in women's reproductive health.

Whether you’re in the depths of infertility, navigating a diagnosis like PCOS or endometriosis, preparing your body for IVF, growing a baby, recovering postpartum, or working to balance your hormones — I can help you figure out what’s actually going on and what to do about it.

I specialize in working with women who have been trying to get pregnant for months or years — often after being told that everything looks “normal,” yet pregnancy still isn’t happening.

For almost 20 years, I have been working with women trying to get pregnant. Most of these women are either preparing for IVF, trying to avoid IVF, recovering from a failed cycle, or trying to understand what’s actually missing before pursuing more medical intervention.

My work is a fertility investigation — not more guessing. Through targeted functional lab testing, personalized nutrition and lifestyle strategies, and high-touch 1:1 coaching, I identify the hidden drivers affecting egg quality, ovulation, hormone signaling, and implantation that standard testing routinely misses.

Whether you’ve been labeled with “unexplained infertility” or you have a diagnosis like PCOS, endometriosis, low progesterone, or poor egg quality — what I know after 18 years and 1,000+ clients is this: it’s rarely unexplained. It’s uninvestigated.

What my clients are saying

The Fertility Code

If you’ve been trying to get pregnant for months – or years – and nothing is working, it’s rarely unexplained. It’s usually that the right things haven’t been investigated yet.

The Fertility Code is my 12-week, high-touch fertility program designed to identify the hidden drivers preventing pregnancy and correct them with a strategic, personalized plan – so you can get pregnant, naturally or through IVF, without losing another year to confusion or failed cycles.

Whether you’ve been told everything looks “normal” or you’ve been given a diagnosis like PCOS, endometriosis, poor egg quality or low progesterone – this program starts where standard testing stops.

Over 12 weeks, we look at your full story, run the right labs, audit your nutrition and lifestyle, and build a personalized fertility protocol tailored specifically to your body, your history, and your timeline. You get 1:1 private coaching, direct access to me between sessions, comprehensive lab review, and an individualized roadmap so you’re never second-guessing what to do next.

More than 90% of the women who complete The Fertility Code go on to conceive.

Stop guessing. Start getting answers.

I can say it all truly worked, because a week ago today (while finishing up week 12), I found out I'm PREGNANT!!!!

"It still doesn't feel real that I'm pregnant, but I know it wouldn't have happened without the changes I learned from you. My experience with The Fertility Code was nothing short of amazing! Even though I work in the medical field and thought I knew a lot from my own research, there were so many things I learned about that I could implement in my fertility journey that I never knew before.

The modules are laid out in a weekly basis so you are never overwhelmed with all the knowledge there is to learn each week. The changes are well defined with examples so it feels easy to get started. There are supporting documents with books, articles that Sarah wrote, and worksheets you can print and follow. The information is very comprehensive and even includes information for your partner to increase his quantity and quality. I can say it all truly worked, because a week ago today (while finishing up week 12), I found out I'm PREGNANT!!!!"

The Fertility
Code

The Fertility Code is a 12-week, high-touch fertility program designed to identify the hidden drivers preventing pregnancy — and correct them with a strategic, personalized plan so you can get pregnant, naturally or through IVF, without losing another year to confusion or failed cycles.

Reasons women work with me:

  • Unexplained infertility — told everything looks normal, but still not pregnant.
  • Poor egg quality or low ovarian reserve — especially if you’ve had failed IVF cycles or are preparing for another.
  • PCOS — irregular cycles, high androgens, blood sugar issues, and the fertility complications that come with them.
  • Endometriosis — managing inflammation, implantation challenges, and cycle irregularities that affect your ability to conceive.
  • Low progesterone or thin uterine lining — often dismissed by conventional testing but a meaningful fertility factor.
  • IVF preparation — optimizing egg quality, hormone signaling, and metabolic health in the 90-day window before a retrieval.
  • Recurrent pregnancy loss — identifying nutritional and hormonal patterns that may be contributing to miscarriage.
  • Painful or irregular periods
  • Low libido
  • Perimenopause and menopause transition
  • Hot flashes, night sweats
  • Low energy, fatigue, burnout
  • Chronic stress
  • Chronic digestive issues: bloating, constipation, IBS, stomach pain, etc.
  • Restoring health and vitality postpartum
  • Optimizing breastfeeding
  • Regaining balance after getting off hormonal birth control
  • Transitioning off birth control
  • Insomnia, sleep issues
