Does a sonagram go tell you gestional age or conceptional age?

A sonogram primarily provides information related to gestational age, which is calculated from the first day of the woman's last menstrual period (LMP). It measures the size of the fetus to estimate how far along the pregnancy is. Conceptional age, on the other hand, refers to the age of the fetus from the time of conception, which is typically about two weeks less than the gestational age.
