Knowing your body’s timing is an important factor when trying to fall pregnant. There are certain days in a woman’s menstrual cycle when the opportunity to become pregnant is higher. For most women this is the six days leading up to and including ovulation. Understanding ovulation and your fertile ‘window’ is important when you and your partner are trying to naturally conceive but also during the IVF treatment process.


What is Ovulation?

Ovulation is a part of a woman’s menstrual cycle when a mature ovarian follicle discharges an egg, the egg will then travel down the fallopian tube where it can be met by a sperm and become fertilised resulting in pregnancy. When a woman is ovulating, they are at their most fertile and during this time a woman’s hormones will be elevated.


The Fertile Window

The chances of pregnancy are highest during the five days before ovulation through to the day of ovulation. These six days are the ‘fertile window’ in a woman’s cycle.

You are most likely to become pregnant if you have intercourse in the three days leading up to and including ovulation.


How do you know when you are ovulating?

It is possible to track when you will be ovulating by working out the average length of your menstrual cycle, with day one being the first day of your period and the last day is the day before your next period begins. Ovulation will happen two weeks before your next expected period. If you have a 28 day cycle (average) you will typically ovulate on Day 14. This is your ‘fertile window’ and your chances of falling pregnant is dramatically increased if you have intercourse in the three days before and when you are ovulating.

Like most things to do with our bodies, your cycles can vary so you can track changes in the timing of ovulation by listening to your body and knowing the signs.
