Please Help...

Ok, so, here's the deal. I have these pimple-like things on my lower abdomen where your pubic hair starts... Not on my vagina, or around my vagina, but it that area above, in between my hips. I was wondering what they are. Because, I dont know how it could be any kind of std because my boyfriend and I were both virgins when we got together and havent been with anyone else. They itch sometimes. They aren't full of puss or oozing or anything gross like that. They just look like pimples are are itchy sometimes. They havent always been there either... I would say they started popping up around july or august, around the same time I started taking bc pills... Could the extra hormones and such have anything to do with it? I just dont know... Anyone have any ideas or should I just ask my gyno? Thanks for helping!
