Experiencing changes in your menstrual cycle or facing fertility concerns? Knowing how to identify low progesterone symptoms and signs is crucial in unraveling the mysteries behind hormonal imbalances and potentially unlocking your fertility.
Progesterone, a vital hormone in the reproductive system, plays a significant role in regulating menstrual cycles and preparing your body for potential pregnancy. Inadequate progesterone production can lead to hormonal imbalances with various implications for your health. By recognizing low progesterone symptoms, you can take control of your reproductive well-being and seek appropriate support when needed.
Progesterone plays a critical role throughout a woman's reproductive life, from supporting pregnancy to regulating menstrual cycles. During perimenopause, progesterone is often the first hormone to decline, sometimes beginning years before other menopausal changes. Understanding symptoms of low progesterone can help you take control of your health at any stage. Want to learn more about progesterone fluctuations? Read our complete guide.
What is low progesterone?
Progesterone, an essential hormone in the female reproductive system, plays a crucial role in preparing the uterus for pregnancy and maintaining a healthy pregnancy. When progesterone levels drop below the normal range, it leads to a condition known as low progesterone.
Low progesterone occurs when the body fails to produce sufficient amounts of this hormone during specific phases (typically luteal phase) of the menstrual cycle or during early pregnancy. It can disrupt the delicate hormonal balance and interfere with the proper functioning of the reproductive system. Understanding the fundamentals of low progesterone, including symptoms of low progesterone, is essential in recognizing its impact on your health and seeking appropriate interventions.

Low Progesterone at Different Life Stages
Symptoms of low progesterone can occur during your reproductive years when trying to conceive, or later during the perimenopausal transition. During reproductive years, low progesterone often presents as luteal phase defects that can impact fertility. During perimenopause, declining progesterone production can create an imbalance with estrogen, leading to new or intensified symptoms.
Causes of low progesterone
According to the American College of Obstetritians and Gynecologists (ACOG), low progesterone can stem from various underlying factors that disrupt the hormone's production and balance within the body. Here are five common factors that can contribute to low progesterone:
- Anovulation: Anovulation occurs when you don’t ovulate: your ovaries fail to release an egg during the menstrual cycle. This can lead to low progesterone levels. Anovulation can occur due to hormonal imbalances, polycystic ovary syndrome (PCOS), stress, excessive exercise, certain medical conditions, or issues with the hypothalamic-pituitary-ovarian (HPO) axis.
- Luteal phase defect: The luteal phase is the second half of your menstrual cycle, during which progesterone levels rise to support a potential pregnancy. A luteal phase defect occurs when this phase is shorter than normal or when there is inadequate progesterone production. This can be caused by hormonal imbalances, ovarian dysfunction, uterine abnormalities, or disruptions in the feedback loop between the ovaries and the brain.
- Hormonal Imbalances: Fluctuations or imbalances in other hormones, such as estrogen or thyroid hormones, can impact progesterone production. Conditions like hypothyroidism or estrogen dominance, where estrogen levels are relatively higher than progesterone, can contribute to low progesterone levels.
- Chronic stress: Prolonged periods of stress can disrupt the delicate balance of hormones in your body, including progesterone. Stress triggers the release of cortisol, which can interfere with the production and regulation of progesterone, leading to lower levels. (Learn how to reduce stress.)
- Certain medications or treatments: Some medications or medical treatments, such as certain types of hormonal birth control, chemotherapy, or hormone replacement therapy, can affect progesterone levels. It's important to discuss any medications or treatments you are taking with your healthcare provider to understand their potential impact on progesterone levels.
- Perimenopause and aging: As women approach menopause, typically in their 40s but sometimes earlier, ovarian function naturally declines. This leads to more cycles without ovulation (anovulatory cycles), resulting in lower progesterone production. This decline often happens while estrogen levels remain relatively stable or fluctuate, creating hormonal imbalance.
Consulting with a healthcare professional, such as a reproductive endocrinologist or gynecologist, can help determine how to test for low progesterone, and if you have it, the underlying cause and guide appropriate treatment strategies for addressing low progesterone levels.
10 Key Symptoms of Low Progesterone
Recognizing the symptoms of low progesterone is crucial in identifying potential hormonal imbalances and seeking appropriate interventions. While individual experiences may vary, here are common low progesterone symptoms:
- Irregular cycles: One of the hallmark signs of low progesterone is irregular periods. You may experience shorter or longer cycles, inconsistent cycle lengths, or missed periods altogether.
- Abnormal bleeding: Low progesterone can lead to abnormal bleeding patterns, such as heavy or prolonged menstrual bleeding, spotting between periods, or breakthrough bleeding.
- Premenstrual (PMS) symptoms: Low progesterone levels can intensify premenstrual symptoms, including mood swings, irritability, anxiety, depression, breast tenderness, bloating, and food cravings.
- Infertility or difficulty conceiving: Progesterone plays a crucial role in preparing the uterus for implantation and maintaining a healthy pregnancy. Low progesterone levels can make it challenging to conceive or increase the risk of miscarriage.
- Changes in basal body temperature: Monitoring your basal body temperature can provide insights into your menstrual cycle. Low progesterone can cause fluctuations in basal body temperature, leading to irregular or inconsistent patterns.
- Fatigue and low energy: Low progesterone levels can contribute to feelings of fatigue, low energy, and a general sense of lethargy.
- Sleep disturbances: Hormonal imbalances, including low progesterone, can disrupt sleep patterns, leading to difficulties falling asleep or staying asleep throughout the night.
- Decreased libido: Progesterone influences sexual desire and arousal. Low progesterone levels can lead to a decrease in libido or a diminished interest in sexual activity.
- Vaginal dryness: Insufficient progesterone can impact vaginal lubrication, leading to vaginal dryness and discomfort during intercourse.
- Changes in breast tissue: Low progesterone levels may cause changes in breast tissue, such as breast tenderness, swelling, or lumps.
Additional Symptoms During Perimenopause
Women experiencing low progesterone during perimenopause may also notice:
- Worsening PMS symptoms
- Night sweats (when combined with estrogen changes)
- Increased anxiety or mood changes
- Brain fog or difficulty concentrating
- Changes in body temperature regulation
- Weight changes, particularly around the midsection
What should I do if I'm experiencing low progesterone symptoms?
If you suspect low progesterone, taking proactive steps can help you get answers and appropriate treatment faster.
Track your symptoms and cycle:
Before seeing a provider, track your menstrual cycle, symptoms, and basal body temperature for at least 2-3 cycles. This data helps healthcare providers make accurate diagnoses. Oova's at-home hormone testing lets you track daily progesterone levels, showing exactly when and how much progesterone your body produces.
Test your progesterone levels:
The most accurate way to confirm low progesterone is through testing. Blood tests from your healthcare provider typically measure progesterone on day 21 of your cycle (or 7 days after ovulation). At-home testing with Oova provides daily measurements throughout your cycle, giving a complete picture rather than a single snapshot.
The timing of progesterone testing matters. For women with regular cycles trying to conceive, testing is typically done about 7 days after ovulation (around day 21 of a 28-day cycle). For women with irregular cycles or those in perimenopause, multiple tests throughout different cycles may provide a more complete picture. Tracking symptoms of low progesterone alongside test results can help you and your healthcare provider identify patterns.
You can test your progesterone daily with the Oova's Hormone Kit to see:
- Exact progesterone levels throughout your cycle
- Whether you're ovulating and producing adequate progesterone
- How your levels compare to optimal ranges
- Data you can share with your healthcare provider
Schedule an appointment:
Consult a healthcare provider who specializes in reproductive health or endocrinology. Bring your symptom tracking data and test results. They can evaluate your symptoms, review your medical history, and recommend appropriate treatment options or refer you to a specialist if needed.
Consider underlying conditions:
Low progesterone is often a symptom of other conditions like PCOS, thyroid disorders, or chronic stress. Your provider may run additional tests to identify and treat root causes.
How do you fix low progesterone levels?
Addressing low progesterone symptoms and levels is important for optimizing fertility and supporting a healthy pregnancy. If you have been diagnosed with low progesterone or suspect it as a potential concern, there are various treatment options available.
Progesterone supplementation
Progesterone supplementation is a common treatment for low progesterone. It involves the use of progesterone medications, such as oral capsules, vaginal suppositories, or injections, to supplement the body's natural progesterone levels.
This helps to support the luteal phase and maintain adequate progesterone levels during early pregnancy. Progesterone supplementation is often prescribed by healthcare professionals and tailored to individual needs.
Fertility medications
In cases of low progesterone, treatment typically focuses on progesterone supplementation and lifestyle modifications that support hormonal balance. Progesterone supplements, available in oral, vaginal, or injectable forms, can help restore normal levels and support a healthy menstrual cycle or early pregnancy.
Lifestyle factors such as maintaining a healthy weight, managing stress, getting adequate sleep, and ensuring balanced nutrition can also play an important role in supporting the body’s natural progesterone production.
Lifestyle modifications
Making certain lifestyle modifications can also have a positive impact on progesterone levels. These include adopting a balanced diet rich in nutrients, managing stress levels, engaging in regular exercise, and getting sufficient sleep.
Maintaining a healthy lifestyle can support hormonal balance and improve overall fertility health.

Identifying and addressing underlying causes
In some cases, low progesterone may be caused by underlying conditions such as PCOS or thyroid disorders. Identifying and treating these underlying conditions can help restore progesterone levels to normal.
A healthcare professional can evaluate your specific situation and recommend appropriate treatment options based on the underlying cause.
It's important to remember that the most suitable treatment for low progesterone levels will depend on the underlying cause, individual circumstances, and guidance from a healthcare professional.
It's crucial to consult with a healthcare professional to receive personalized guidance and support tailored to your specific needs.
The Bottom Line
Whether you're trying to conceive, navigating irregular cycles, or experiencing the hormonal shifts of perimenopause, recognizing symptoms of low progesterone is the first step toward taking control of your health. This hormone affects everything from your menstrual cycle to your mood and energy levels.
Remember that hormone testing and tracking can provide the clarity you need to work effectively with your healthcare provider. You don't have to accept feeling unwell as "normal." With proper evaluation and treatment, many women find significant relief from their symptoms of low progesterone.
Frequently Asked Questions About Low Progesterone Symptoms
What level of progesterone is considered low?
During the luteal phase, progesterone levels below 5 ng/mL are typically considered low, while normal levels range from 2-24 ng/mL. Testing should be done about 7 days after ovulation for the most accurate results.
Should I test my progesterone if I have irregular periods?
If you're experiencing irregular periods along with other symptoms of low progesterone, testing can provide valuable information. However, single-point testing may not capture the full picture with irregular cycles. Consider working with a healthcare provider who can recommend appropriate testing timing or cycle mapping.
Can younger women experience low progesterone?
Yes. Women in their 30s and even 20s can experience low progesterone, particularly if they have conditions like PCOS, high stress levels, or thyroid disorders. Symptoms of low progesterone aren't limited to perimenopause or fertility concerns.
How does low progesterone affect weight?
Low progesterone can contribute to weight changes in several ways. It may affect metabolism, increase water retention, and when combined with relative estrogen dominance, promote fat storage. Additionally, the sleep disturbances and mood changes associated with low progesterone can indirectly impact weight through changes in appetite and activity levels.
What's the difference between low progesterone symptoms during fertility years versus perimenopause?
During reproductive years, low progesterone typically causes consistent luteal phase problems affecting fertility and PMS. In perimenopause, progesterone production becomes erratic, leading to unpredictable symptoms that vary from cycle to cycle, often accompanied by other hormonal fluctuations.
Can I get pregnant with low progesterone?
Yes, but it may be more challenging and increases early miscarriage risk. Many people with low progesterone successfully conceive with treatment like progesterone supplements, ovulation medications, or lifestyle modifications.
Can low progesterone fix itself?
Temporary stress-related low progesterone may resolve once stress decreases, but chronic low progesterone from conditions like PCOS or luteal phase defects usually requires intervention. If symptoms persist for more than 3 cycles, consult your healthcare provider.
How long does it take to raise progesterone levels?
With progesterone supplementation, symptoms may improve within 1-2 cycles, while lifestyle changes typically take 3-6 months to show results. Treating underlying conditions like PCOS may take 6-12 months for full hormone regulation.
Can lifestyle changes really impact progesterone levels?
Yes. While lifestyle changes may not completely resolve progesterone deficiency, factors like stress management, adequate sleep, maintaining a healthy weight, and proper nutrition can support your body's natural hormone production and potentially improve symptoms.
What foods help increase progesterone?
Foods rich in vitamin B6 (salmon, chickpeas, bananas), vitamin C (citrus, bell peppers), zinc (pumpkin seeds, oysters), magnesium (leafy greens, almonds), and healthy fats (avocados, nuts) support natural progesterone production. However, diet alone usually isn't enough to correct significant imbalances.
