Yeast infection?? omg help.?

Well...so I had a bacterial infection a few months ago. I went to see my doctor and she did a check up to make sure I didn't have an std and tha test came out gud and I don't have an std. My doctor prescribed me something that took tha infection away but then after it went away I got my period, when my period went away tha bacterial infection came back. So I got my doctor to prescribe that stuff to me again and it went away again. But now for tha past week I feel like there's another problem and of course this is ryte after my period again. When I had tha bacterial infection, tha discharge had a really bad odor but it never itched. Now I'm guessing this might just be a yeast infection because it itches really bad but doesn't really have a bad odor, but my discharge is kind of thick and clumpy, a little bit like cottage cheese. Also, there is a tiny sore on it but I think its just an in-grown hair from shaving because I've had this same sore in tha same spot before but it was forever agao when I was like 15 and I'm 18 now. When I had it when I was 15 it just went away on its own in like a week and that's what its doing now. It doesn't hurt or anything, only if u apply pressure to it. If this is a yeast infection, what can I do to get rid of it as fast as possible, without having to go to tha doctors again becuz I'm really starting to get extrememly embarrassed becuz I also have to tell my mom too. I'm at my lowest n I'm just soooo tired of this I want it to be gone for gud. Just give me some ways to get rid of all this shyt permenantly before I just really go insane, its makin me sooo depressed n I can't even enjoy lyfe ryte now. Just somebody help please. N if you're gonna be ignorant about this just don't put shyt on here. Thank you..
