I was on the birth control pill for a good three months but then stopped in July this year. In the same month I had my period twice, once in the beginning and then again at the end of the month. It's not December and I still haven't seen my period since ! But now Ive been having DARK discharge/spotting for almost 3 weeks now , I'm not pregnant (that I know of) but I'm also having a vaginal itching too, I don't know what's going in with me but last time I've been to the doctor , which was in October, the pregnancy test came out negative and it was only bv found. What's happening??
