Are there certain days in my cycle that I can't get pregnant?

Yes, but they can be tricky to track. The fertility awareness methods use different techniques for tracking your cycle—ideally you’ll use a combination of them to help with accuracy and success. They all involve observing changes in your body and calculating where you are in your menstrual cycle. This takes effort and commitment, so before you decide this is the method for you, be sure you really understand what you’ll need to do. Be prepared not to have sex for at least seven days out of every month, or to use a backup method like condoms.
