Due date calculator — If you have regular monthly menstrual cycles and know the first day of your last menstrual period, you can determine when your baby is due by using the following calculator.
Ultrasound — If you do not have regular monthly menstrual cycles or do not know when your last menstrual period started or when you conceived, you will need to have an ultrasound examination to determine your due date. This examination should be done before 12 weeks (3 months) of pregnancy because ultrasounds done after the fourth to fifth month of pregnancy are not very reliable for predicting due date.
