Cosmosis i dont have personal experience but can tell you all the ladies i know with boys in real life all had FAST heart rates..150-170 their whole pregnancy.
Nann3r, DD3 was always 130-140..140 when she was active 130's when she was sleepy...DD4 was 140-150 the whole pregnancy. DD1 was always 150-160 and DD2 was always 170..she used to scare me cause she never seemed to settle..it transfered to her after womb life though so at least now we know whats up with that..she has had anxiety from a very very young age. Who knows if thats why her heart rate was so high in utero but good reason to believe so now.
ps nann3r..your dd1 is GORGEOUS..what beautiful hair!!!!!
