While listening with my fetal Doppler, I have actually heard my baby’s heartbeat speed up quite rapidly on two separate occasions. Both times, coincidentally, I had finished drinking about 1/2 can of Diet Pepsi. Has anyone else actually heard the heartbeat speed up while listening in a short period of time and know what this could be attributed to? Could it be sensing the Doppler and reacting to the sound waves?
Also, I am 12 weeks 2 days pregnant and have been hearing the heartbeat since 9 weeks 3 days with a home fetal Doppler. On ultrasound at 8 weeks 2 days, the heartbeat was 180. It has stayed between 160 and 170 since then.
