I need some help here. A couple days ago I had sex, and i noticed after, and throughout the next couple days, my vagina was really sure. I thought it was just from the sex, as it was rather rough. a couple days later it was a little itchy, then yesterday i woke up and it burned to pee. It was the worst feeling ive ever had down there. theres was two or three bumps and it was really itchy. i didnt know if i had a uti so i went to the store and bought pills for the burn and cranberry pills. Now this morning ive noticed a lot more pimple like bumps all over my vagina. What could this be? a yeast infection? an STD? or a uti?? Please help!
