Hello,
First of all, I am very sorry about your
miscarriage. Usually your
period should show up within 6 weeks after a
D and
C, so yours could show up at any time. I'd probably wouldn't start to worry until after the 6 weeks. You could take a home pregnancy test right now but I am not sure how accurate it would be. As far as the mass goes, that would have me a little worried and I would go for a second opinion if all this doctor said was he "thought" everything was ok.
