This story gives me some hope.
I had my last ultrasound on 1/11 - Friday. At a prior ultrasound (on 12/28) my husband discovered a second baby (yes, the technician missed it). The doctor said we should expect to lose one baby as it is much smaller than the other.
We went into our appointment on 1/11 fully expecting to have lost one of the babies, but they were both there, and both measuring at 7w1d. Anyway, we were overjoyed to see both babies still there, but our hopes were quickly dashed by the ultrasound technician when she announced that neither twin had a heartbeat. The doctor came in and confirmed that there indeed was no heartbeat in either twin. She was amazed that both twins had continue to develop and were looking otherwise quite healthy with their own amniotic sac and placenta (but sharing a gestational sac).
The doctor said that we should expect to miscarry, and it would likely happen within a week. She said that she would schedule another ultrasound for January 18th, but they were quite certain the pregnancy was no longer viable because 85% of pregnancies have heartbeats by 6 weeks.
Anyway, here I am, a few days later, I still feel nauseous, my breasts are still very sore... I still feel pregnant. I'm hoping that my story will be a positive story on Jan 18th. Either way, husband and I have opted to let nature take its course and wait it out.
