Menstrual Calendar 2025. The phases of your menstrual cycle. All you have to do is to enter the starting date of your last period and the average length of your period cycle.

The due date calculator estimates the delivery date of a pregnant woman based on her last menstrual period (lmp), ultrasound, conception date, or ivf transfer date. When using the last menstrual period, we add 14 days.
