Why does your baby's heartbeat vary so much around 12 weeks because the heartbeat was around 130 and now at 15 weeks it is at 158 bpm and should you worry that it is so high now?

Answer 1

Don't worry. Think how much your heartbeat varies if you are moving around. A sleeping baby may have a heartbeat between 120-130 and if it is moving a lot it may be between 140-160. Also if you have a mild fever it will put up both your and your baby's heart-rate. == The further along you get in your pregnancy the higher the heartbeat will get.....you are right in the target range for your baby's gestational age. If you go for "monitoring" later on in your pregnancy, you will get to see it elevate to the high 180's as the baby moves, then come back down to the 150's - 160's, as you approach delivery the heartbeat will drop slightly. (monitoring is such a pain in the butt but it really puts you in tune with your baby!)

Answer 2

170 is a little higher than normal at 13 weeks of pregnancy but you may have had a raised pulse yourself because of infection or nervousness. Actually this is not true. It is very normal for the baby's heartbeat to be in the 170's this early in your pregnancy. My research shows that several people have even had their baby's heartbeat in the 180's in the early stages, and had normal healthy pregnancies and baby's. "Normal" is 140-160, however Doctors have found 170 - 180's to be normal too.
