had rough unprotected sex..next day after bath my vagina started burning.day after that i saw light pink spotting.very light.std or rough sex?
STD's generally take a while to show symptoms and can sometimes be symptom-less. I can tell you from experience that it's probably from the sex being too rough as it has happened to me a time or two before. The burning is probably due to microtears of the vaginal wall and the blood is probably from that as well!
