The key is for her to know she is ovulating so that intercourse can be time correctly to either ensure fertilisation or to avoid it. This must be done carefully because the timing of ovulation varies greatly from one woman to another and, for some women, from one month to the next.

Fertilisation of a woman’s egg is more likely from intercourse before or during ovulation than from intercourse following ovulation. It usually occurs during a six-day period that ends in ovulation.

Using either a manual chart (FREE) or using the Ovusoft fertility planning tool will help you to recognise your fertility signs.
