A member asked:

With a normal pregnancy, all ultrasounds including ones in the 1st trimester showed lmp 10/15/12. could conception have occurred after 11/7/12?

A doctor has provided 1 answer

Pregnancy sono: If the ultrasounds were done in the first trimester and all confirm the 10/15/12 lmp, then there is little chance that conception occurred after 11/7/12. The first trimester ultrasound is usually sensitive to +/- 3 days.
