7 Natural Signs of High Fertility Every Woman Should Know

Understanding Your Fertility: A Window Into Your Health

One thing that I wish more women understood is that your fertility is so much more than your ability to conceive — it’s a reflection of your overall health. Whether you’re actively trying to conceive, being proactive about the future, or just looking into balancing your hormones naturally and optimizing your health, being able to recognize the signs that you’re fertile is an important first step. The good news? Your body provides clues every single cycle and understanding them can help you to not only optimize your reproductive health, but also identify if something is off and needs attention.

Here are seven key signs of high fertility that every woman should be aware of:

1. Regular, Predictable Menstrual Cycles

A healthy menstrual cycle is the foundation of optimal fertility. While every woman’s cycle is unique, a cycle length between 25 and 35 days that is consistent from month to month is a positive indicator of hormonal balance and ovulatory function.

Why Regular Cycles Matter

Regular cycles suggest that your body is producing and regulating estrogen and progesterone properly, allowing for ovulation and a sufficient luteal phase (the phase after ovulation that supports implantation). Irregular cycles or cycles that are either too long or too short may indicate hormonal imbalances, high stress, or underlying conditions like polycystic ovary syndrome (PCOS) or thyroid dysfunction.

I often hear my clients dismiss when their cycles are irregular, because many women assume irregular cycles are simply "normal for them," but in reality, they often point to deeper imbalances. Then, when we begin to work on cycle regulation through nutrition, lifestyle changes, and targeted supplementation, they notice improvements not just in cycle predictability but also in energy levels, mood, and overall well-being.

Actionable Steps:

Start tracking your cycles with a fertility awareness app or a simple paper chart. Keep notes on your cycle length, symptoms, and lifestyle factors like stress, sleep, and diet. If irregularities persist for three or more cycles, consider hormone testing to check for underlying imbalances.

2. Optimal Cervical Mucus Patterns

Cervical mucus is a powerful, real-time indicator of fertility because it signals when you’re ovulating (AKA when you’re in your fertile window). As ovulation approaches, estrogen levels rise, leading to the production of clear, stretchy, egg-white-like cervical mucus that helps sperm survive and travel through the female reproductive tract.

How to Identify Fertile Cervical Mucus

Non-fertile mucus: Thick, sticky, or creamy (low estrogen).

Fertile mucus: Clear, stretchy, slippery, wet, watery — can resemble raw egg whites (high estrogen, ovulatory phase).

Actionable Steps:

If you consistently notice little to no cervical mucus each cycle, it may be due to low estrogen, dehydration, or nutrient deficiencies. Supporting hydration, consuming healthy fats, and addressing digestive health can improve cervical mucus quality.

3. Healthy Basal Body Temperature (BBT) Shifts

Tracking basal body temperature (BBT) can provide valuable insight into ovulation and the health of your luteal phase.

BBT shifts after ovulation due to the hormone progesterone, a warming hormone that’s only produced after ovulation. A sustained temperature increase indicates that ovulation has occurred and that your body is producing adequate progesterone to support implantation and early pregnancy. A lack of this temperature shift could suggest anovulation (lack of ovulation), while a short luteal phase with an early temperature drop may indicate low progesterone levels, which can have a huge impact on fertility.

What a Healthy BBT Pattern Looks Like

Before ovulation: BBT is lower (97.0–97.7°F).

After ovulation: BBT rises by at least 0.5°F and stays elevated for at least 12 days.

What to Watch For

If BBT doesn’t rise, ovulation may not be occurring.

If BBT drops too soon, progesterone levels may be low.

A well-supported luteal phase with stable temperatures suggests that your body is producing enough progesterone to support implantation, a key marker of high fertility.

Actionable Steps:

BBT tracking is one of the most powerful tools for understanding your fertility, but it’s easy to feel overwhelmed by the numbers. In my course, The Fertility Code, I walk you through everything you need to know to track and interpret your BBT, along with other key fertility signs, so you can confidently use this method for natural conception or cycle health.

4. Strong Libido and Energy Levels

Let’s just say that mother nature is sneaky. I say this because her evolutionary goal is for you to become pregnant and to stack the cards in her favor she increases your libido every cycle around ovulation, basically ensuring that you do the deed when you’re in your fertile window. This heightened sex drive during ovulation is mostly due to testosterone and estrogen peaking around this time.

Why Energy and Libido Matter

A sudden drop in libido or chronic fatigue are both red flags because they can represent a whole host of underlying issues impacting fertility, like thyroid disorders, adrenal dysfunction, hormone imbalances or nutritional deficiencies.

Now don’t get me wrong, some energy fluctuations throughout the cycle are normal and expected, but these should be gentle, not extreme. If you find yourself exhausted mid-cycle or disinterested in intimacy, it may be a sign that stress, diet, or hormone levels need attention.

Actionable Steps:

If you notice low libido or extreme fatigue, assess your stress levels and ensure you're getting enough B vitamins, magnesium, and protein in your diet. Try stress-reducing activities like gentle yoga, deep breathing, or nature walks to support adrenal health.

5. Balanced Hormones with Minimal PMS Symptoms

Mild PMS symptoms can be normal, but anything extreme like bloating, mood swings, severe cramps, or breast tenderness more often than not indicate an underlying hormonal imbalance.

Signs of Balanced Hormones

• Minimal mood swings throughout your cycle.

• Stable energy levels without crashes.

• Mild cramping that doesn’t require heavy pain management or affect your ability to go throughout your day. Missing classes or calling off work? — Yeah, definitely not normal.

Actionable Steps:

To naturally support hormone balance, focus on an anti-inflammatory diet rich in leafy greens, cruciferous vegetables, and fiber to support estrogen metabolism. If PMS symptoms persist, consider cycle-specific seed cycling or gentle liver detox support with dandelion tea or milk thistle.

But my best tip is to test your hormones so you know exactly what you’re dealing with and can implement a targeted plan. That’s exactly what you get in The Hormone Reset Package.

6. Clear Skin and Healthy Hair

Your skin and hair are external reflections of internal health, especially when it comes to nutrient stores, hormonal balance and fertility. When your body produces the right levels of estrogen, progesterone, and androgens (like testosterone and DHEA), it supports healthy hair growth, clear skin, and overall vitality.

Why Skin and Hair Reflect Fertility

• Balanced Estrogen Levels: Estrogen helps maintain skin hydration, elasticity, and collagen production, giving the skin a healthy, youthful glow. It also regulates oil production, reducing breakouts.

• Optimal Androgen Balance: Androgens (such as testosterone) play a role in hair growth, but excessive levels can lead to hair thinning, breakouts, and conditions like polycystic ovary syndrome (PCOS), which can impact fertility.

• Progesterone’s Role: This hormone counterbalances estrogen and androgens, promoting clear skin and a stable mood while supporting a healthy luteal phase.

• Thyroid Health: Since thyroid hormones regulate metabolism, they also influence hair growth cycles. Hypothyroidism (low thyroid function) can contribute to hair thinning, dry skin, and even cycle irregularities.

• Insulin Sensitivity and Skin Health: Balanced insulin levels help regulate blood sugar and prevent excess androgen production. High insulin can contribute to conditions like insulin resistance and PCOS, leading to acne, excessive hair growth, and ovulatory issues that impact fertility.

Actionable Steps:

For clearer skin and stronger hair, focus on balancing blood sugar by pairing protein and healthy fats with every meal. If acne or hair thinning is persistent, consider checking androgen levels (like testosterone and DHEA) and optimizing your zinc, vitamin D, and iron intake.

7. Optimal Digestion and Nutrient Absorption

Gut health plays a significant role in fertility, influencing everything from hormone metabolism to nutrient absorption and immune function. The gut is responsible for breaking down food and extracting the vitamins, minerals, and essential fatty acids needed to produce hormones like estrogen, progesterone, and thyroid hormones. If your digestive system is compromised—whether due to poor microbiome diversity, leaky gut, inflammation, or food sensitivities—your ability to absorb these critical nutrients is reduced, which may negatively affect fertility.

Since estrogen is metabolized in the gut and liver, poor digestion can contribute to estrogen dominance, which may affect ovulation and progesterone production. You can learn more about the gut hormone connection here.

Signs of a Healthy Gut for Fertility

• Regular, well-formed bowel movements, ideally once per day

• Minimal bloating, gas, or discomfort after eating

• Stable blood sugar levels throughout the day

• No persistent food intolerances or sensitivities

Actionable Steps:

If you experience bloating, irregular bowel movements, or food sensitivities, start with a gut-friendly diet by including fermented foods (like sauerkraut and kimchi), reducing processed sugar, and eating fiber-rich foods. If symptoms persist, consider functional testing with a comprehensive stool analysis, so you know exactly what’s going on with your gut. That’s exactly what I offer in The Digestion Reset Package.
