Question

what happen when egg is not fertilised

Answer 1

Every 28 days or so, one matureegg is released from the ovary. This is called ovulation. After theegg is released, it moves into the fallopian tube where it stays for about 24 hours. If the egg is not fertilized during that time, theegg disintegrates (breaks down) and menstruation (your period) begins 2 weeks later.
