Why do I Need to Understand Ovulation?
Understanding your ovulation cycle can help you time intercourse in your "fertile window" and give you a better chance of getting pregnant quickly and naturally.
Ovulation is when an egg (ova) is released into your fallopian tubes, ready to be fertilized by your partner's sperm. If the egg is not fertilized, it will be discharged along with the lining built up in your uterus (menstruation).
After it is released, the egg is only viable for 24 hours. A man's sperm can survive in the fallopian tubes for up to six days. Which means that you are fertile for the six days leading up to the day of ovulation.
Being able to identify the day you ovulate takes the guess work out of trying to get pregnant. It means that you can time intercourse in the six days leading up to ovulation. This is known as your "fertile window". There are a number of strategies you can use to identify when you ovulate and keep an ovulation chart. Find out more below:
