Hi all, I was under the impression that your heartrate increases during pregnancy due to the increased blood volume, however mine has dropped, my resting heart rate before pregnancy was between 60-70 bpm now its sitting low 50's and sometimes drops to 48bpm. It will rise to around 70-80bpm when I'm up and about but soon drops again. I'm 8 weeks pregnant, so I'm starting to worry something is wrong. I'm feeling fine besides the constant all day and night nausea. Does anyone else have a low heart rate?
