Hi! I m 20 yrs old. My menstrual pattern has always been very irregular. Varying from having no period in a year, 6 mos or so. I got my first period when I was 14 or 15 and my second cycle was normal until the third cycle which did not occur after only 9 mos or so. I m a virgin so pregnancy was never a problem. I ve had an ultrasound done and there was no problem found. I ve also been changing the stuff I use to genuine organic products and still no result. My ob gyn prescribed Hemarate FA(or FE) but the discharge was so little to none. It look almost like spotting. I ve done some internet research and I ve read that this could be prolactinoma. I hope you can help me. Thank you!
