I have small ovarian cysts. tests carried out by a gynaecologist, found nothing irregular, so why am i having irregular & long periods (4wks long)?

PCOS: Poly cystic ovarian syndrome (pcos) may be the cause of your symptoms. This occurs generally in overweight females. The extra weight leads to an imbalance in estrogen and Progesterone and thus the ovaries create small multiple cysts. Irregular periods can also be a result. Diet, e excise, and weight loss are the solution. Metformina diabetic medicine is also helpful. Ask your this.
