My boyfriend and I were messing around and I had my pants on (NO PANTIES) and I think he may have had his thing out and was (dry humoing me) at the time I was paranoid that he had c***** or pre C****** or touched it then touched me down there this happened on the 25th at about 1245am I went to pp and took next choice on the 27th at 245.. Then 2 days after I kept feeling like I had to pee after I already did, I asked if he had c****** or pre and he said no a week later I am bleeding but have some pain in my lower stomach I am worried but everyone tells me I am fine that I am just stressing out I took 3 pregnancy test all negative I am worried stressed any help I would appreciate....
