I just heard the heartbeat (LOL, lying on the bathroom floor, but I didn't care). I calculated it to be about 164. Yay! It was reassuring, since I've been worried because I was feeling better. I found it right away, low, right above the pubic bone on the right side. YAY!!!!
Oh, my co-worker friend (she's a nurse) snuck it for me. She told me about it while I was pregnant with Andrew, so now it's in the back of my mind. I knew that once I made 10 weeks, I'd be able to hear it.
