Hi - I was tested for any STDs as I was bleeding constantly on the pill came back that I had chlamydia - took 4 Zithromax at one time and waited 8 days to have sex - me and my partner were both treated same way at the same time that was just over 2 weeks ago Now I'm on depo injection and have come on my period again today (I never used to bleed on it before, apart from some spotting) I'm worried that this means I still have it because I was bleeding before that's why I got tested - or do you just think this is completely normal?
