Ok I'm having a problem with brown discharge I can't tell when i'm on my period or when I'm not and its very frustrating. A month or so ago me and my boyfriend had sex (unprotected) but i'm not pregnant anyway he looks down and says "You're bleeding babe" I go into the bathroom and check and its brown not red brown. Now three months before that night I had a baby girl and received my depo shot the day after my daughter was born. I still had a small period but it was never brown it didnt start until after i had sex with my boyfriend he was concerned because a few more times after we had sex again my discharge was still brown so after a long time of pain and sleepless nights i went to the doctor i was diagnosed with a UTI which explains the pain. I was given three antibiotics and now my discharge is thicker and heavier is it the antibiotics causing me to still have this brown discharge or is it the UTI hasn't completely gone I'm still taking the antibiotics by the way please help I need to know whats going on with my body I feel like i'm no longer in control!!!!!!!!!
