I have had 3 m/c at varying stages in early pregnancy, not in a row though.
I am on aspirin and clexane which I think has helped, and am now 22 wks so am presuming I will carry to term as everyting is looking good now.

miraclebubba- how many weeks were your m/c? I think if you previously managed to carry twins to a healthy gestation thats a good sign, but i agree you need to see a dr in case there is something you can take to help. Best of luck
