Hi.

I've been bleeding for 4 weeks, the colour of the blood changes from brown, to red to a pinkish colour. Last week Thursday I had bad cramps and there after a blood clot came out, the same thing happened yesterday. A doctor prescribed provera to stop the bleeding yet nothing has stopped. I have back cramps too. I am on a 2 month injection though. Kindly advise on what the problem could be?
