I had a D and C this morning and am having heavy bleeding. They said to call your doctor if you're filling a pad every hour which I was, so I called and he prescribed me a medicine that he says will cause pain and cramping but stem the bleeding. I'm scared to take it because I don't like pain. Has anyone else taken that medicine? Do you think he's being overly cautious telling me to take the medicine? Maybe it will let up in a few hours? I'm scared. Help!
