Okay so, around a month ago I was drunk and got with a guy on campus and didn't use protection (stupid, I know). Anyway, a week later I had "tonsillitis" but was certain it was an STI. I went to the doctors and they put me on antibiotics, it cleared a little but then came back (They don't test for STI'S) As well as taking the antibiotics, I took the morning after pill (lasts up to five days after) and a few days after this, I received the implant. I was experiencing other symptoms such as fever and abdominal pain so I decided that I would go to get tested for STI's to which it came back positive for Chlamydia. I've now been on antibiotics for this and still have had the abdominal pain (have a few days left of antibiotics). I'm worried since I've missed my period but I'm not sure if that's due to having the implant or not or whether the morning-after pill didn't work? or maybe my body is confused with the amount of medication I've been taking over the last couple of weeks? Also, does anyone know how long I'm likely to have abdominal pain for and if this should go as soon as the antibiotics have finished? I'd appreciate any support, I'm not quite sure what to do
