I Lost My Period Trying to Be Thin for My Wedding”: What Every Active Woman Needs to Know About Hypothalamic Amenorrhea and Infertility

Written By Cynthia Donovan

When my story was featured in People, it opened up a conversation that far too many women are silently living through.

I thought I was being “healthy.”
I thought discipline, clean eating, and pushing harder in the gym were things to be proud of.

Instead, I lost my period, struggled with infertility, and became disconnected from my body in ways I didn’t fully understand until years later.

But what the article only briefly touches on is the deeper issue behind so many missing periods in active women: hypothalamic amenorrhea (HA).

As a registered dietitian specializing in missing periods, HA, and fertility recovery, I now help women around the world recover their cycles, restore ovulation, and rebuild trust with their bodies, without giving up movement forever.

What Is Hypothalamic Amenorrhea (HA)?

Hypothalamic Amenorrhea is a condition where the brain essentially suppresses reproductive function due to perceived stress on the body.

This stress can come from:

  • Undereating

  • Excessive exercise

  • Weight loss

  • Emotional stress

  • Chronic dieting

  • Obsessive food rules

  • Poor sleep and recovery

  • A combination of all of the above

When the body does not feel safe, it downregulates reproduction.

This means ovulation may stop entirely, estrogen levels can drop, and your menstrual cycle disappears.

For many women, this begins subtly:

  • Missing a few periods

  • Irregular cycles

  • Low libido

  • Constant fatigue

  • Feeling cold all the time

  • Digestive issues

  • Anxiety around food

  • Obsession with workouts

  • Infertility struggles later on

And because our culture often praises restriction and excessive discipline, many women don’t realize anything is wrong until they want to get pregnant.

Why Missing Your Period Is NOT “Normal” for Active Women

One of the biggest misconceptions I see is women being told:

  • “You’re just athletic.”

  • “It’s normal for runners.”

  • “You’re lucky you don’t get periods.”

  • “Just go on birth control.”

A missing period is not a badge of fitness.

Your menstrual cycle is a vital sign.

If you are not ovulating consistently, your body is communicating that it does not currently have enough energy or safety to support reproduction.

Even if your labs look “normal.”
Even if you’re eating “healthy.”
Even if you appear fit and strong on the outside.

The Link Between HA and Infertility

Infertility is often the wake-up call that brings women to me.

Without ovulation, pregnancy cannot happen naturally.

Many women spend years:

  • Chasing weight goals

  • Training harder

  • Eating cleaner

  • Ignoring missing periods

…only to discover later that their hormones have been suppressed for years.

This was part of my own story too.

I remember watching friends get pregnant while I secretly wondered if my body would ever be able to do the same. Mother’s Day felt painful. Baby showers felt isolating. I felt disconnected from femininity and frustrated with myself for not being able to “fix” it through more discipline.

But the answer was never more control.

The answer was learning how to nourish my body enough to feel safe again.

Can You Recover From Hypothalamic Amenorrhea?

Yes, absolutely.

I’ve now worked with hundreds of women worldwide who have:

  • Recovered their periods

  • Restored ovulation

  • Improved fertility

  • Gotten pregnant naturally

  • Returned to exercise in a healthier way

  • Found freedom with food and movement

Recovery is not just about “gaining weight.”

It is about restoring adequate energy availability, reducing physiological stress, improving nervous system safety, and rebuilding a healthy relationship with food, exercise, and self-worth.

For some women, recovery includes:

  • Eating more consistently

  • Increasing carbohydrates and overall calories

  • Pulling back on intense training temporarily

  • Reducing compulsive movement

  • Prioritizing sleep and recovery

  • Healing perfectionistic tendencies

  • Learning that rest is productive too

Why Working With a Dietitian Who Specializes in Missing Periods Matters

Not all nutrition advice is appropriate for women with HA.

Many women I work with were previously told to:

  • Eat less

  • Track more macros

  • Intermittent fast

  • “Balance hormones” while staying under-fueled

  • Keep pushing through workouts

Unfortunately, this often worsens the problem.

As a registered dietitian specializing in hypothalamic amenorrhea and infertility, my approach focuses on helping women:

  • Recover their menstrual cycle

  • Improve fertility outcomes

  • Maintain an active identity in a healthier way

  • Build confidence around food

  • Heal their relationship with exercise

  • Create long-term hormonal health

You do not need to earn food.
You do not need to punish your body into health.
And you do not need to lose yourself to recover your period.

Signs You May Have Hypothalamic Amenorrhea

You may want to seek support if you:

  • Lost your period for 3+ months

  • Have irregular cycles

  • Exercise intensely

  • Fear weight gain

  • Constantly think about food

  • Have a history of dieting or restriction

  • Struggle with infertility

  • Experience stress fractures or low bone density

  • Feel exhausted despite “healthy habits”

Even women in larger bodies or women who are not underweight can develop HA.

This is about energy availability and stress on the body, not just body size.

My Mission Today

My experience with losing my period and struggling with infertility completely changed the direction of my life.

Today, through my programs, podcast, and educational content, I help active women recover their periods while becoming stronger mentally, physically, and emotionally.

Because getting your cycle back is about far more than hormones.

It is about reclaiming your life from fear, control, and constant self-punishment.

And if you are currently struggling with a missing period, I want you to know this:

Your body is not broken.
It is adapting.
And getting your period back AND becoming a Mom when you want to IS POSSIBLE.

Frequently Asked Questions About Missing Periods and HA

Can you get pregnant with hypothalamic amenorrhea?

Without ovulation, natural conception becomes very difficult. However, many women fully recover ovulation and fertility once adequate nourishment and recovery are restored.

How long does HA recovery take?

Recovery timelines vary depending on nutrition, exercise, stress, and individual physiology. Some women recover within months, while others may take longer.

Do I have to stop exercising completely?

Not always. But many women benefit from temporarily reducing exercise intensity and volume while improving nutrition and recovery.

Can you have HA at a normal weight?

Yes. HA is not only about body weight. Many women with HA appear healthy or fit externally but are still under-fueling relative to their activity and stress levels.

Is birth control a treatment for HA?

Birth control may create a withdrawal bleed, but it does not address the root cause of hypothalamic amenorrhea.

Final Thoughts

If your body is asking for rest, nourishment, and safety, listening is not weakness.

It may actually be the strongest thing you ever do.

And if this story resonates with you, know that you are not alone. There is a path forward, and recovery is possible with the right support.
