Good luck, antsy! I'll be thinking of you.
Armywife - I didn't have an official OB/GYN appt until 8 weeks and they probably wouldn't shown me anything at that point. What happened for me was that I originally started with one practice and they have you come in around 6 weeks to "confirm" (urine test) and then schedule you for your first prenatal after that. When I went in for that confirmation visit, I showed them my chart and told them I ovulated at day 19 (not the "standard" 14), so they wanted to do a dating ultrasound to make sure I was right - kind of annoying to be doubted about my own body, but we got to see the heartbeat then around 7 weeks. Anyway, so for a number of reasons, I ended up switching practices and had my first real prenatal appt yesterday at 12w1d. That's when we got to hear it on the doppler. It was pretty cool - really sounded like a train, like I'd read here! There were also some kind of... bouncy noises (not sure how else to describe it) and my midwife said they were kicks! And don't worry, the next few weeks will fly by. I honestly don't know where weeks 8-12 went.
