I've just had my third miscarriage (plus a few chemical pregnancies). First one I miscarried at 8 weeks after seeing a heartbeat the week before, I had a D&C but I think it would have happened naturally if I'd waited a day or two. Then I had DD. Second one I had a missed miscarriage that never developed and eventually had a D&C at 9 weeks. Then I had DS. My third miscarriage everything was fine until my 18 week scan and the baby had died. I delivered him but then needed a D&C for the placenta.
I don't know if there could be a reason or if it's just bad luck? Clearly my body can have successful pregnancies but I just miscarry a lot. My Dr didn't recommend getting any tests or anything as they're not consecutive so they're probably just bad luck but I'd be interested to know if anyone else has experienced the same and discovered a reason why.
