And i didn't get my results back from my NT scan but i got the report and i have just read it, the doctor didn't go through with it with me just printed it out for me to read myself.

This is what it says:

TA ultrasound shows normal intrauterine pregnancy with single sac and fetus, dimensions of which are consistent with gestational age of 12.5 weeks +/- 1 week, which corresponds to dates. Fetus appears normal with heart rate 155bpm, CRL 60mm and nuchual translucency 1.7mm. Liquor volume is normal. Placenta is posteria. No maternal abnormality seen. The combined first trimester trisomy risk assessment will be sent as soon as available.

My first question is whats CRL and is 60mm normal? and is 1.7mm normal?

The doctor did explain that that measurement is matched up with my blood work thats how they work out if its normal or not but does that seem normal.

I also found out that i have never had Chicken Pox so am worried about that. I have been told to stay away from anyone who may have it which is hard when they are most contagious before they get spots. So i might just stay home
