Important!

Gestational age is the age of the baby starting from the date of fertilization until birth. To make it simple, the gestational age can be estimated by indicating the first day of the mother's last menstrual period. This calculation assumes that the fertilisation occurs on the 14th day of menstrual cycle. 

As a result, this method has a margin of error by ±2 weeks.
