No fertility window?

Jasmine
I just recently started using Glow in order for my fiancée and I to avoid having children until after we are married. It's what we want to do for our best interest.
​I am on the pill but I'm very confused when I look at my calendar on the application and see nothing for my fertility window.
​I understand that it could be because of my being on an oral contreceptive but shouldn't there still be a fertility window?
