In September of 2012 I got chlamydia for the first time. In July 2012 I got checked for any Std's and it came up negative, in September 2012 I got checked again and it came up positive, I started dating this guy in August and we had intercourse and everything. So I took the pills and waited 7 days to have sex again. He said he got checked out and he said he was clean, so I believed him.. And I had a check up in December again and I caught it again.. Now I know he was lying. I have not cheated or anything. And so now it's January, and we're having protected sex, but I just went to the bathroom and it hurt to pee again, I think I got it again.. How did this happen? We were careful.. And can I still get pregnant after having chlamydia this many times?
