Today I went in for my second appointment and they used a thing, like a miniature u/s, too hear the heartbeat. I can't remember what it's called. There's no pic, it's just sound. Anyway, they tried it for 10 minutes before we finally heard anything! Talk about scary! If we didn't hear anything, I would have had another pic u/s done, but luckily they found him/her. So, all is going well.
