【實用醫療app】POG Calculator|最夯免費app-綠色工廠好玩App

This application helps in telling you your POG and all trimester dates including expected delivery date(EDD) on the basis of your LMP.By convention, pregnancies are dated in weeks starting from the first day of a woman's last menstrual period (LMP). If her menstrual periods are regular and ovulation occurs on day 14 of her cycle, conception takes place about 2 weeks after her LMP. A woman is therefore considered to be 6 weeks pregnant 2 weeks after her first missed period.A woman's obstetric date is different from the embryologic date (the age of the embryo). The obstetric date is about 2 weeks longer than the embryologic date.
