Progesterone

Progesterone is a female sex hormone that plays a crucial role in the menstrual cycle, pregnancy, and fetal development.

In females, progesterone supports menstruation and helps maintain the early stages of a pregnancy. Too little progesterone can cause complications with pregnancy or produce side effects similar to menopause. Too much progesterone can cause fatigue, bloating, breast tenderness, mood swings, headache, nausea, irregular periods, increased risk of blood clots, and seizures.
