The estimation of pregnancy dates is important for the mother, who wants to know when to expect the birth of her baby, and for her health care providers, so they may choose the times at which to perform various screening tests and assessments,such as serum screening, assessment of maturity, and induction of labor for postdate pregnancies.
The 3 basic methods used to help estimate gestational age (GA) are menstrual history, clinical examination, and ultrasonography.

When an ultrasound is done between weeks 12-22 of pregnancy, gestational weeks are considered as being within 10 days of accuracy.
At around seven weeks of pregnancy, it’s reasonably common for women to have their first ultrasound.
