So Ok. For One I'm Not Sexually Active. I'm A

So ok. For one I'm not sexually active. I'm a virgin. Two I'm just coming off of heroin. (30 days tomorrow) so that being said I haven't had my period in almost 10 months, and was in the past few months taking antibiotics (extras from before that I never finished) whenever I was worried I was getting an abcess. It causes discharge but I blamed the antibiotics. It is like cream colored/yellowish and smells funny, and I feel like my vag is swollen like in the back where it connects to my butt but it doesn't hurt its just more difficult in the shower when I'm washing myself. Any ideas what could be going on?

Also and I didn't know this cost money or I wouldn't have even bothered. Ive never been to the gynecologist and at the moment I have no money or insurance or anything. So please answer my question. I don't know if I should be worried or if it's my hormones or the drugs or what...
