I am in a similar situation. My doc said 11 days ago that I was 5 weeks 6 days according to my u/s and my husband and I saw the flicker on the monitor of what appeared to be the baby's hb. I asked the doc what it was and he said he thinks its the heartbeat but wouldn't confirm. I then had another u/s yesterday and we saw no heartbeat. Doc immediately wanted to schedule a d&c. I told him I was not ready as it all seems to be happening so fast. According to my calcs, I was 6 weeks 4 days yesterday (I'm fairly certain as I was taking chlomid) I now have an appt scheduled for a second opinion with another doc next Thursday. Am I in denial that it could just be a dating issue, or is there still hope?
