I'm wondering if any of you ladies have gone in for your first U/S and measured farther along than you actually were? I just read two threads about the girls who are measuring 2 weeks earlier their LMP... I can understand that way, ovulation being a tricky thing to pinpoint AND how long it takes for implantation to actually occur, but can things go the opposite way, too? I got my BFP 6 days before my missed period... so now I'm wondering if when I go in for my first U/S at 5 weeks if it's possible to be measuring at 6 weeks. I want to hear a heartbeat soooo badly!!!
