Ovulation Time and Chance of higher Pregnancy

MYTH BUSTING: A Women can get Pregnant any time of the month (MYTH). A Womem can only get Pregnant on a few days during her Menstrual Cycle(FACT).

Ovulation is when a mature egg is released from the ovary. The egg then moves down the fallopian tube where it can be fertilised. If sperm are in the fallopian tube when the egg is released, there is a good chance that the egg will be fertilised, creating an embryo, which can grow into a baby.


Because eggs and sperm only live for a short time: Sperm live for around five days. Eggs can only be fertilised for around 24 hours (one day) after being released from the ovary. 

Eggs and sperm need to come together at the right time for fertilisation to happen to create an embryo.

A female can get pregnant at any time during her menstrual cycle. The likelihood of pregnancy is highest during ovulation, which is typically days 10-14. Intermenstrual bleeding can occur between periods.

What are the chances?

Having sex as close as possible to the time of ovulation increases the chance of pregnancy.

If a woman has sex six or more days before she ovulates, the chance she will get pregnant is virtually zero.

If she has sex five days before she ovulates, her probability of pregnancy is about 10 percent.

If she has sex on the day of ovulation, or the two days before, the chance of getting pregnant is around 30 percent.  

These are average figures and depend on a woman’s age.

The ‘fertile window’ depends on the length of the menstrual cycle, which varies among women. The ‘fertile window’ is the day an egg is released from the ovary (ovulation) and the five days beforehand. Having sex (intercourse) during this time gives you the best chance of getting pregnant.
