Hi mam, My LMP was 28/10 /2017. I had my ultrasound on 22/12/2017. My cervix length 5.4 cm, CRL 7 mm, heart beat 138bpm and the gestation sac size was smaller than the CRL in pregnancy. Doctor asked me to take scan after two weeks. May I know the sac size will get increase after a week or not. Am worrying a lot. Kindly please help me.
