this is near the opening of my vagina. i have not been sexually active for about a month because i havent seen my boyfriend in a month. this popped up out of the blue. i at first thought it was a tear or cut but upon taking this picture it made me really worried. i cant tell if its a yeast infection because i was told that yeast infections can cause things that look like this too. what do you guys think? Please help . i cant get to a doctor till at least the end of the week.
