wow they can be very different cant they, i was worried that my baby's heartbeat was a little too high but some of you girls are very close behind!
at 9w0d mine was at 173, at 10w3d it was 172.
Had scan done yesterday heartbeat was 176 (11 weeks) and 179 (8 weeks).
at 10w1d the HB was at 161
Ever since 9w4d mine has been about 166 give or take every day ;)
