The last time I had a period was in January/Feburary of 2010 its now November 1 2010 and I havnt got one period or even started spotting..NOTHING! I was on birth controll pills for one month and then quit and recently ive had alot of thick white discharge, my back will be sore some days for no reason or if i stand up too long, even in the shower while washing my hair my back will start hurting, also i have some cramping and especially when i go pee my stomache begins to hurt even more and sometimes my nipples will get sore too. Im sure i dont have a uti or anything im just really confused of why my period hasnt came in so long. My boyfriend and I have been trying for two years to get pregnant and nothing so far and it really gets me sad because it seems like everyone around me can get pregnant but me....Any advice of what i should do??
