Thank You, Raspberries. I had ultrasounds at 5 weeks 2 days and 6 weeks 1 day. We did not see the heartbeat at 5 weeks but did see the fetal pole and normal growth for five weeks. We did see the heartbeat at 6 weeks and 1 day, so I'm sure of my dates. I see my doctor next week. So far, she has not talked about changing my due date, but I am scheduled for a c-section on 2/16/16.
