You : You could have anovulation, a polyp or growth in the uterus or cervic, or perhaps uterine fibroids. A starting point in the evaluation is often an ultrasound that will demonstrate the polyps or fibroids, perhaps a follicular ovarian cyst or polycystic ovaries.

Too frequent menses: Menstrual periods every two weeks are too frequent and a GYN MD needs to assess why. There are several reasons that this can occur including but not limited to a too active thyroid gland function. (hyperthyroidism)
