Ovulation Predictor / DDLady

Calculation of the pregnancy due date or the expected date of delivery (EDD) of your baby is possible by using this unique pregnancy due date calculator. Just enter the 1st day of your last menstrual period below and you can find the expected date of delivery or your due date. Pregnancy, on average, lasts 267 days (38 weeks) from conception. If you positively know your conception date, you can add 267 days to it for your due date. A simple formula for calculation of your due date is also provided after this pregnancy due date calculator.
Ovulation calendars and ovulation calculator Every month in a human female's ovary, a mature ovarian follicle ruptures and discharges an ovum. This process is called ovulation. Ovum is the female gamete or the cell responsible for reproduction. When an ovum fuses with a sperm, the process is called fertilization and when this fertilized ovum implants itself in the uterus, it is called conception.The few days around the time of ovulation are the fertile period. A female can conceive only during those few days because the ovum is discharged between the middle of the two menstrual cycles (approximately 14 days after the first day of your last menses) and survives just for 2-3 days without fertilization. So considering the life span of a sperm and the ovum, the fertile period is calculated using the ovulation time. A female is considered fertile 2 to 3 days before and after ovulation.
