I agree with Steph, you really should see your dr. It doesn't seem right to bleed that long. I'm surprised they didn't want to check your HCG levels to make sure they went down to 0.
You really need to get into the dr. Have you taken a HPT?
i was seven weeks along i havent been back to the dr.since the mc
I would call my dr. asap...It could all kinds of things. Did they check for an ectopic pregnancy? You might still be pregnant, or you might have retained tissue from the m/c that could cause problems too...How far along were you? You can take a HPT and see if it comes up positive...
