Fertility Awareness

Fertility awareness methods are all about tracking your menstrual cycles to determine your fertile window, or the days that you can get pregnant. To do this, you have to pay attention to your body, its patterns, and the way it changes when you are ovulating (releasing an egg). People who use this method can estimate when it is safer to have sex if they don’t want to become pregnant.

This method can be used for avoiding pregnancy or trying to become pregnant.
