Conception calculator

A woman is usually able to get pregnant for about 5 days each month, when ovulation occurs. On average, ovulation occurs 12 to 16 days before the menstrual period begins. Because sperm can live for 3 to 5 days in a woman's reproductive tract, it is possible to become pregnant if intercourse occurs several days before ovulation. The Pregnancy Conception Calculator can help to find out the pregnancy conception date based on the pregnancy due date. The pregnancy conception day is the day when your baby is conceived.
