Is It Normal To Have A Six Week Pregnancy?
Hi I am suppose to be 6 weeks pregnant, however, last week I had an ultra sound and I measured at 4 (all that was visible was the sac). My last period was December 3rd and I probably concieved on the 17th. Is this normal to have a six week pregnancy only measuring at four weeks?

Hallow Dear,
The conception occurs 14 days after the last menstrual period.
The pregnancy duration is counted from the date of last menstrual period (LMP) while the ultrasonography estimated the period of gestation based on the size and age of the baby; i.e. period of pregnancy from the conception. Hence there is difference of about 2 weeks in the initial phases of pregnancy.
I hope this helps you.
