Pregnancy, Pregnancy Calculator, Conception Calculator

The Conception Calculator assesses the conception windows and the corresponding due date based on your personal biological cycles. Conception is the initiation of pregnancy, or when an egg and sperm form a union. It normally occurs in the ampulla of the uterine tube. In vitro fertilization (IVF) is a process by which conception occurs outside the body. If conception occurs via sexual intercourse, sperm can normally live inside a woman for three to five days, or up to seven days. However, sperm mobility decreases after three days. The best time to get pregnant is during the three-day "window", or two days before to the ovulation day.
