The first day of a woman's period is day 1 of the menstrual cycle. Once she starts her periods, 1 egg develops and is released during each menstrual cycle. After ovulation, the egg lives for 24 hours. Pregnancy happens if a man's sperm meet and fertilise the egg. Sperm can survive in the fallopian tubes for up to 7 days after sex. Occasionally, more than 1 egg is released during ovulation. If more than 1 egg is fertilised it can lead to a multiple pregnancy, such as twins.
