chlamydia infection
"I started a new relationship with my current boyfriend and I felt something not right after having unprotected sex with him the first time.  I went to get tested and unfortunately it came back positive. They gave me 2 500mg pink pills. I was so sick to my stomach that time... so nauseous with diarrhea. So did he. But we didn't wait long enough to have sex and got it one more time. Took it again last night around 10pm and woke up day (7:45am) with bad stomach pain, nauseous and diarrhea- so did my boyfriend. So please wait to have sex again !!!!!! Better to take it once and have the pain/diarrhea than to double take it for not  waiting."
