What is the length of time calculated from the first day of the LMP?

Explanation:
Gestational age is the length of time counted from the first day of the last menstrual period. This dating method expresses how far along the pregnancy is in weeks (often with days) and provides a baseline for assessing fetal development and estimating the due date. Ovulation typically occurs about two weeks after the LMP, so gestational age roughly corresponds to fetal development minus about two weeks. This is distinct from the other terms: the gestational sac is the fluid-filled structure seen on ultrasound early in pregnancy; gravidity is the total number of pregnancies a woman has had; parity is the number of those pregnancies carried to viability.
