Hii my last period date was 17 august .I m 5 week 5 days pregnant according my sonography scan (MSD) 0.90cm corresponding to 5 weeks 5 days and foetal pole and yolk sac are not visualised yet.is this normal or there is some issues in pregnancy ..because I think mostly sac noted in 5 week .In my previous pregnancy the sac noted in 5 week 6 days ..but this time it is not visualised yet. I had miscarriage though in my 8th week in previous pregnancy because of stop of baby growth in 6 week .so I m bit scare this time too , please guide me thank you
