A couple of weeks ago my vagina started itching really bad. I went to get tested for STIs. I havent gotten my results back. I am really nervous because when I went to the restroom this morning I notice a bump that looks like a pimple. I popped it, and I have had one before now. Is it an STI? Is there a way to prevent the pimples? Are the pimples and the itching connected? I have my vagina and I am sexually active. Does that have anything to do with it? Should I be worried?
