I am 21 and I was on BCP for 3 years and I stopped taking them in Dec 2006 and my periods started gettting lighter and shorter and irregular since I stopped taking them and now my I haven't had one at all for two months. I went to my gyn and he checked everything only to say that I wasn't ovulating every month and recommended I take BCP to make my periods regular but I didn't want to start back because I was going to start trying to get pregnant. What should I do ? Also my aunt has endo Is that hereditary?
