Oh my gosh, that was so cool! I've been grinning like a cheshire cat all afternoon! We ended up getting an ultrasound out of the deal (yay ultrasounds!); we were only expecting to hear the baby's heartbeat. At first the midwife couldn't find the heartbeat, and I was getting really nervous about it. But she kept saying that my uterus was probably just tilted backwards or something. So she brought in the ultrasound machine and holy cow, there's a baby in there! It was so cute, s/he was jumping all over the place, kicking his legs and punching with his arms. And we could see the tiny heart beating! After that, the midwife was able to find the heartbeat - 170 beats per minute!
I also told my boss and my coworkers, so the cat's out of the bag. I know I'm still not out of the first trimester yet, but I feel like things are going to be fine. My coworker - the one with the duct tape on his shoes :) - was really excited, it was cute.
