I was told that if the placenta was more than 3cms away from cervix, not considered an issue for monitoring as they grow up with the growing uterus.

Dunno about the other bits, but the heartrate is fine if between around 120 and up to 180 if bubs is really active at the time. At this gestation 120 - 150 is the "normal" end. At 12 wks mine was 169 bpm and at morphology 139 bpm.

Hope that helps a little bit!
