What is ovulation?
This is when an egg is released from one of your ovaries. Sometimes more than one egg is released and this tends to happen within 24 hours of the first egg. While the egg is released the lining of your womb (uterus) begins to thicken and the mucus in your cervix thins. This allows the sperm to swim through your cervix easily as they make their way to the egg.
The egg lives for 12-24 hours after it is released, if it is not fertilised by a sperm it leaves the body along with the lining of your womb, this is a woman’s period.
