I have had abnormal bleeding now for the last 2mnth. Iv been on the injection for the last 8 year n iv Neva had a period while being on it. Iv bled again today but it was different this time to usual...the blood is a lot darker n a bit heavier than usual plus when i was wiping myself I noticed sum skin/fleshy stuff and the pains in the bottom of my back are worse than usual. Iv seen the doctor n theyv advised me for a smear because it was over due and iv got it this Friday. But I'm worried because I had to have this smear earlier than usual because my last 1 had abnormal cells n I had to have the loop biopsy. Do you think they could have missed sum thing and Its cancer
