:kiss I heard that if the fetal HR is above 140 BPM that it is a girl. Has anyone ever heard this or something like it? My dtr is having her first, she is 16 wks. Baby's HR is 160 BPM. Her doctor has not done an US yet. This is my first grandchild, I'm really getting excited. By the way, I'm a Hospice RN, know 0 about OB. Thanks.
