Chance of pregnancy ?

Suzanne
So yesterday was the last day of my fertile window and I noticed something on the app. It told me I had an 8% chance of pregnancy and I'm assuming that it meant chance of getting pregnant on that day because of it being the fertile window. I was wondering, though, is there anything on the app that tells you if you may or may not be pregnant or something that tells you to think about getting a test before I would go and waste a pregnancy test
