Premenstrual Syndrome (PMS) and Premenstrual Dysphoric Disorder (PMDD) are conditions causing physical and emotional symptoms in the weeks before menstruation. They are caused by hormonal fluctuations, particularly low progesterone levels during the luteal phase of the menstrual cycle. The Progesterone Blood Test is the most important test for identifying hormonal imbalances contributing to PMS and PMDD symptoms.
PMS and PMDD are caused by hormonal fluctuations during the menstrual cycle, particularly involving progesterone and estrogen. During the luteal phase (the two weeks before your period), progesterone levels should rise after ovulation and then fall if pregnancy does not occur. When progesterone levels are too low or the ratio between estrogen and progesterone is imbalanced, it can trigger physical symptoms like bloating, breast tenderness, and fatigue, as well as emotional symptoms like mood swings, irritability, anxiety, and depression. Women with PMDD experience more severe symptoms that significantly interfere with daily activities and relationships.
The Progesterone Blood Test is the most important test for PMS and PMDD because it measures your progesterone levels during the luteal phase of your cycle when symptoms typically occur. Low progesterone during this time is a key hormonal imbalance that contributes to both physical and emotional PMS and PMDD symptoms. The test should ideally be done about one week after ovulation (around day 21 of a 28-day cycle) when progesterone levels should be at their peak. Your healthcare provider can use these results along with your symptom patterns to determine if hormonal imbalance is the root cause and develop a targeted treatment plan that may include progesterone supplementation, lifestyle changes, or other hormonal therapies.
You should get tested if you experience recurring symptoms in the week or two before your period that improve within a few days after menstruation starts. Common signs include severe mood swings, irritability, anxiety, depression, bloating, breast tenderness, fatigue, food cravings, or sleep problems that interfere with your work, relationships, or daily activities. Testing is especially important if your symptoms are severe enough to disrupt your life (which suggests PMDD rather than typical PMS), if over-the-counter remedies are not helping, or if you want to understand whether hormonal imbalances are contributing to your symptoms so you can pursue targeted treatment options.
What this means
Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
Recommended actions
Increase resistance or strength training
Prioritize 7–8 hours of quality sleep per night, try to reduce stress
Include more zinc- and magnesium-rich foods (like shellfish, beef, pumpkin seeds, spinach)
Consider retesting in 3–6 months
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
