Hi everyone, this is a very long and confusing one. I was on the contraceptive injection for 3 & half years, I was due my last one in January but desided to come off it due to a hormone imbalance caused by depo & it got too much for me so it was the right move for me. However I experienced a lot of withdrawal symptoms, eg severe mood swings to the point I didn't recognise myself, a lot of abdominal pain, really sore boobs (because of the hormone imbalance during my time on the injection I was producing breast milk, this has now gone so that's why they were so sore) I haven't had a period since I started the injection which was October 2009, however the past two weeks on and off I've been getting brown discharge, it changes from dark Brown to light brown, and I'm concerned I may be pregnant as I know about implantation discharge, but I know it could be caused by my period trying to start up again.. but I'm in a lot of pain and my boyfriend has been great about it but I do feel bad for him. I don't want to worry him as I already thought I could be pregnant a few months ago & it was a false alarm & I dont want to do it again.. what should I do, I'm only 18 & don't want to go to the docs just incase it is my period trying to start..
