Signs You Might Have Low Progesterone

Key takeaways:

  • Progesterone is essential for ovulation, menstrual cycle regulation, mood, sleep, and energy.

  • Low progesterone is often linked to anovulation (when ovulation doesn’t occur) and can have widespread effects on health.

  • Recognizing the signs can help you take action sooner, and real-time tracking makes it possible to see what’s really happening in your body.

Progesterone may not get as much attention as estrogen, but it plays a key role in keeping your body and mind working optimally. This hormone is essential for regulating your menstrual cycle, stabilizing your mood, supporting sleep, and even maintaining energy levels. But when progesterone levels drop too low, it can lead to a variety of symptoms that affect how you feel day-to-day.

Low progesterone is more common than you might think, and recognizing the signs is the first step to restoring balance. Let’s break down what low progesterone looks like, why it happens, and how you can support your body naturally.

Signs of low progesterone.

1. Irregular or missed periods.

Progesterone helps keep your cycle on track. Without enough of it, the uterine lining may not build or shed properly, leading to unpredictable, anovulatory, or absent periods.

2. Spotting between periods.

Spotting before a period often signals insufficient progesterone. Progesterone is essential for stabilizing the uterine lining, and a deficiency may cause it to shed prematurely.

3. PMS symptoms that feel worse than usual.

Mood swings, bloating, and irritability are all signs of premenstrual syndrome (PMS). But when progesterone is low, these symptoms can feel amplified. This happens because progesterone calms the nervous system, so a deficiency can make PMS feel harder to manage.

4. Difficulty sleeping.

Progesterone is known as the “calming hormone” because it helps your body relax and promotes better sleep. Low levels of progesterone may contribute to insomnia, restless nights, or waking up feeling unrefreshed.

5. Fatigue and low energy.

Low progesterone can leave you feeling drained, even after a good night’s sleep. Without enough of this hormone, your body may struggle to maintain steady energy levels throughout the day.

6. Mood changes and anxiety.

Progesterone has a calming effect on the brain, thanks to its interaction with GABA, a neurotransmitter that helps regulate anxiety and stress. Low progesterone can result in heightened anxiety, irritability, or feelings of overwhelm.

7. Trouble conceiving or maintaining pregnancy.

Progesterone is critical for preparing the uterine lining for implantation and supporting early pregnancy. Low levels may make it difficult to conceive or increase the risk of miscarriage in the first trimester.

What causes low progesterone?

Low progesterone can result from a variety of factors, including:

  • Chronic stress. High cortisol levels may interfere with progesterone production.

  • Age. Hormone levels naturally decline as you approach menopause.

  • Overall health. Certain conditions, like polycystic ovary syndrome (PCOS), can affect ovulation and progesterone levels.

Supporting healthy progesterone levels.

1. Manage stress.

Chronic stress shifts your body’s resources toward producing cortisol (your stress hormone) instead of progesterone. Mindfulness practices like meditation, deep breathing, and yoga can help lower stress and improve hormone balance.

2. Eat a hormone-supportive diet.

Your diet plays a huge role in hormone production. Incorporate foods rich in:

  • Magnesium. Spinach, almonds, and dark chocolate

  • Zinc. Pumpkin seeds, shellfish, and legumes

  • Vitamin B6. Bananas, salmon, and chicken

These nutrients help support the production of progesterone and maintain overall hormonal health.

3. Prioritize quality sleep.

Good sleep is essential for hormone regulation, including progesterone. Aim for 7–9 hours of restful sleep per night, and create a bedtime routine to signal to your body that it’s time to wind down.

4. Track your hormones.

Understanding your hormone levels is key to making informed decisions about your health. Monitoring progesterone levels in real time helps you identify patterns and track the impact of your lifestyle changes.

Take action for hormonal balance.

Low progesterone can affect everything from your mood to your energy to your ability to sleep well. Recognizing the signs and making small, intentional changes to your lifestyle can help manage the symptoms and support your body’s optimal functioning.
