They still haven't been able to hear a HB with a doppler with this baby. She moves around too much!! Also I have an anterior placenta which is why they can't hear it earlier in PG. When I was at my OB appt at the hospital at 16 weeks she was unable to get a HB on this baby and put a u/s on and could see baby moving around & a HB but was unable to even measure it because this baby was too active. HTH!
