Hello doctor .I m 17 and I ve been bleeding now for 7-8 months and it all started off when I had an abortion last september, after that I had the pill injection for the first time and 2 weeks after that I started bleeding quite heavy, then it slowed down, I had two more pill injections after that and its not stopped once, so I didn t go for my next one last month and I m still bleeding, I ve now gone itchy and sore down there. What s wrong with me?
