I’m scared I have an STD

Last year at my yearly checkup, I got the all clear. However, I’ve always had a little bump right next to the entrance of my vagina. Last week, I accidentally popped it. I’m the kind of person who can’t leave pimples and stuff alone so I keep messing with it. After the initial pop, it got huge and painful and then popped itself again. I then of course squeezed it to clear it out. But I feel my squeezing irritated it and now it’s bigger than before and feels rock solid. I can’t go to my normal gyno until December and I’m so scared and I have no one to talk to. I don’t know what to do and I keep sending myself into anxiety attacks over it. My boyfriend would kill me if I had one (went aren’t sexually active and the original bump was there before him). I just. I don’t know who to talk to or what to do.

I’m sorry if this isn’t right for here.
