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 to prevent pregnancy. They all involve observing changes in your body and calculating where you are in your menstrual cycle. This takes effort and commitment (and a predictable cycle), 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 7 days out of every month or to use a backup method, like condoms, during your fertile days.
