So, because this pregnancy is driving me to become a nutcase, I ordered a doppler the other day. It came today, so I tried to find the heartbeat. I wasn't able to find it, and our 2.5 year old was so interested in what the heck I was doing. He then threw his shoe on my belly, and I just gave up. I just got him interested in something, so I tried again. I found it!!!! For literally 3 seconds. It was 164 -- exactly what it was at our u/s! The baby must have moved, because I wasn't able to find it again. Oh well. I'm so relieved. I already got my money's worth out of the doppler.
