My daughter delivered her still born baby at 4 1/2 months in 03/09/2018. She thinks she became pregnant again around July 21, 2018. She had a non-vaginal ultrasound at 9 weeks and their was no heartbeat. Her CLR measured 1.1cm (11mm) Is it possible that her hormones were not regulated yet and she could be 7 weeks instead of 9 weeks? Based on her measurements, should she have heard the heartbeat during her ultrasound? The doctor is suggesting a D/C, should she do another ultrasound or could a hCG test determine the viability of the baby?
