Pregnancy is an exciting journey, and understanding your timeline is crucial for planning prenatal care and tracking fetal development. The Last Period Pregnancy Calculator on our website helps expectant mothers estimate their pregnancy progress, including due date, trimester, and gestational age, based on the first day of their last menstrual period (LMP). This professional, user-friendly tool ensures accurate and timely pregnancy planning.

It is widely used to track fetal growth, schedule prenatal visits, and prepare for labor and delivery.
