I had my second appointment on Tuesday and everything went well until the doctor tried to hear the heartbeat. He said at 10 1/2 weeks that he *should* be able to hear it. He would think he'd hear it but then it would go away. So he sent me in for an emergency viability ultrasound, which scared the crap out of me. I've already had a dating ultrasound and everything was perfect with a heart rate at 170, so the thought that the baby could have died made my heart sink. Thankfully, the baby is fine and everything still looks perfect. The heart rate is now at 164 and he/she was wiggling around a whole bunch, which is probably why the doctor couldn't hear it. Here are pics from my first and second scans.
First: 8w 3d
Second: 10w 3d
You can see the arms and legs now. Such a change in just 2 weeks!
