Menopause happens when the ovaries stop releasing estrogen and progesterone and no longer ovulate. The clinical definition is when someone has not had a period for 12 consecutive months. The transition period leading up to menopause is called perimenopause, which can last several years. In this transition period, many experience irregular cycles and a variety of symptoms associated with hormonal fluctuations.If after continuous testing for 3 days, 2 or more of your FSH results are 25 mIU/mL or more, it means that you may be transitioning into menopause. If your results are higher than 50 mIU/mL, it shows that menopause has either already occurred or is imminent. Consult a doctor for next steps and for immediate support.
