My midwife could not hear a heartbeat at 11 weeks, or at 12 1/2 weeks, but it seemed it could be because my uterus was tipped back, so she sent me to a doctor for an ultrasound and it was perfectly clear right away, that in fact, our baby was no longer alive. My husband and I talked about options with our midwife and the doctor; I wasn't sure if I wanted to wait for a spontaneous delivery or have surgery, the D and C. When I learned that it could take up to 12 weeks for the spontaneous "miscarriage", I knew I did not want that -- to wait and wonder for this painful delivery anytime, anywhere. Two days after we learned of our baby's death, I had the D and C. The hospital staff was wonderful to us, compassionate, expert. Our doctor told us we could request to have the baby's remains returned to us so that we can have a burial ceremony.
My heart goes out to you and I hope you can find out soon what is happening with your baby. This discussion board is very helpful.
