I had an ultrasound scan at 6 weeks 5 days GA(LMP).

I had an ultrasound scan at 6 weeks 5 days GA(LMP).
The CRL(Hadlock) value is 0.35 cms.
Is this normal? Is my baby growing at a normal rate or is the CRL low and indicates that low CRM made lead to miscarriage?
Report says FH and FM seen. Cardiac pulsations seen. Yolk Sac seen. Gestation sac intact.
The most likely cause is that you are not as far along as you think. Maybe your cycle was long or you ovulated late. The single best predicator of a healthy pregnancy is a normal heart rate.

Hello Dr. K,

My LMP is 31st March and since I used ovulation predictor kit, I know I ovulated on 14th April.

As I mentioned the fetal pulsation was detected.


Your best predictor of fetal viability is the heart beat. The crl is less than the 5% which does increase the risk of loss. There is no data on how much the risk is increased. A followup scan would be helpful.
