Good evening! I would like to ask a question. I am six weeks pregnant, I had an ultrasound, and I was told that my future baby's heartbeat is 80 beats per minute. This is my first pregnancy. I was told that the embryo/fetus's heartbeat should be faster, but the fetus's heartbeat was around 80 beats per minute. Is my baby's heart beating too slowly? Or could it be normal at such an early stage of pregnancy, and will the heartbeat speed up later? Is this normal? Has this happened to anyone? Please help. Thank you in advance. Sincerely, Aydana.
