Conception Calculator
This conception calculator can be used to estimate the conception windows and the corresponding due date based on biological cycles. Conception is the initiation of pregnancy when an egg and a sperm form a union. It normally occurs in the ampulla of the uterine tube. In vitro fertilisation (IVF) is a process that conception occurs outside the body. If via sexual intercourse, sperm can normally live inside a woman for 3-5 days or up to 7 days. However, the sperm mobility decreases after 3 days. To get pregnant, the best three days window to have sexual intercourse is from two days before to the day of ovulation.
The results of this calculator are estimation based on average.
