কীভাবে Pregnancy গণনা করবেন

Pregnancy কি?

A pregnancy calculator estimates your due date, current gestational age, and trimester based on your last menstrual period (LMP) or conception date. Pregnancy lasts approximately 40 weeks (280 days) from the LMP, though normal term is considered 37–42 weeks.
