Pregnancy occurs when a mature ovum (egg) is released through the ovarian follicle (wall) and into the fallopian tubes, where it is then fertilized by a man's sperm. Ovulation usually occurs 10 to 14 days after menstruation, and the implantation of a sperm into the ovum can typically take 6 to 12 days from the date of ovulation. If you add these figures up you will see that a woman will become pregnant before a period is due.
