My a question is based on my last missed period I'm supposed to be 10 weeks....but having my second u/s, doctor says the yolk looks partially deflated and to have more blood work done. Yesterday my OB did the Doppler and both doctor and I heard a heartbeat. At first it kept moving around and was hard for her to locate...but eventually a heartbeat was heard... Could my OB be mistaken and was hearing my heartbeat instead? Right now everything is making believe there is no baby.....
