Hormone Changes in a Woman’s Body
The most important groups of hormones for women are estrogens (especially ß‐estradiol) and progesterone. In a healthy female body they balance each other so phases of the menstrual cycle occur regularly. When one is going down, the other is going up. Their synchronized cycle repeats about every month (25 to 35 days). When the balance between estrogen and progesterone is lost, your body may act in unpredictable ways.
