Conception occurs during the part of a womans menstrual cycle called ovulation. Doctors consider day 1 of a menstrual cycle the first day of a womans period. Ovulation usually occurs around the midpoint of a womans menstrual cycle.
What is considered conception date?
The conception date refers to when a baby was conceived. Since sperm can live inside the vaginal canal for three to five days, conception can take place up to five days after sexual intercourse. Fertilization depends on ovulation and can occur within 12-24 hours from the release of the egg (ovulation).
What happens in the first days after conception?
Between four to six days after conception, the fertilized egg will develop into a blastocyst and burrow into the uterine lining, attaching itself firmly. In this early stage, the embryo develops a yolk sac, which provides its first nutrients. But as the tiny being grows, it will turn to its host (you) for sustenance.
