I am a 24 year old female just looking for some admire on what could be my problem. I used to be taking the cerazette contraceptive pill but it was making me have awful mood swings and emotions all over the place. Before I came off this I started to have brown discharge which I thought was withdrawal bleeding, but I also get quite a lot of constant pain in my left abdomen. I had my period 2 weeks ago and this week the brown discharge has come back on monday, I woke up in a lot of pain and was in pain for the next 2 days. The pain has eased off but I still have the brown discharge. What could this be? Is this something I should be concerned about?
