Ignore the heartrate at all costs...unless its too low or too high for health reaosns..otherwise..as long at its beating within the regular zone for "babies" your good!!! My kids were all over the place...
DS#1...138 (at u/s & only had one other count once before labour and delivery)
DS#2...138 (1st & only count...145 @ u/s)
DS#3...145-155...several counts
DS#4...145...generally the same at all counts & u/s
DS#5...138-145...up and down the entire thing
the baby I am carrying now...I got 170 first time @13 weeks with my own doppler, 148 @ dr. office, 150 at home, 140 last week at dr., and it was 143 @ u/s and it a girl!!!
Good luck adn don't give up hope...the heartrate is just a generalization and is proived wrong many times!!!
