My LMP started 2/10/10 according to all the doctors that I've seen/talked to, I'm due 11/17/10 and should be about 8 weeks along. I had an ultrasound at the Options 360 clinic on Tuesday and the baby should have been about 7.5 weeks. She took measurements of the baby and the baby was measuring at 6.5 weeks. Putting my due date at Nov. 25th. How is it possible that I'm only at 6.5 weeks when in all technicalities I should be 8?
You may have ovulated later than you thought or had late implantation. As long as the doctors are seeing a healthy baby /heartbeat etc.. you should be ok.
