I'm over the moon with relief after my second doctor's appointment! I posted about this weeks ago, but after my first appointment I was a wreck. The baby measured at 4 weeks when I was supposed to be 5 weeks, 5 days pregnant and the doctor couldn't find the heartbeat. After talking to people on this board and some friends with similar experiences, I felt much better, but still worried deep down that the sac would be empty at the next u/s.
Today the first thing the doctor said was, "Wow, look how much the baby grew!" We could see and hear a strong heartbeat and the baby measured at 8 weeks, 5 days which puts me right on target with my due date!
