I have no history of any STD's and concerned. I have been married for a few years now and my husband and I have had issue of infifelity on his part. After the incident we both got tested for the range of std's and thank god all came back negative. About two weeks ago I got what seemed to be a hair bump in my pubic area. I did not realize it was there until rubbing one day and it busted and bloodied up a piece of tissue as I wiped myself. Then this past weekend I noticed that I had a bump on the inside lip portion of my vagina. There is no discomfort with it I am just concerned. Then this morning I ended up with diarrea. Have gone to the bathroom several times. Does this sound like an STD, cyst or some other issue I should consider?
