Don't be concerned. It is okay. Your baby could have been sleeping. The heartbeat is going to vary. A healthy fetal heartbeat is 120-180. Your baby is fine. I know it is hard not to stress. I have been feeling better the last three days and I am scared to death something is wrong. Worry is what mother's do.
I think sometimes it depends on how active the baby is. I know with my son, whenever he was resting, his heart rate would be 135 and when he was very active, it was 145-150. The baby could have been sleeping when the nurse listened on the doppler. It constantly changes and is never a perfect rate at any given time. I'm sure if she had listened again, it could have been a little higher than the first time. I wouldn't worry about it. When I went for my u/s...the tech told me they are only concerned if the heart rate were to go below 100. You sound just fine.
