Fertility

I am a little confused when it comes to the new update. So if I go to the big circles that are blue pink or red it will say you are 3% chance of pregnancy or whatever but when I fill out my daily log the fertility in the upper left hand corner goes up with each thing I update... not mattering with what answer I would give it would go up the same amount... Is that really my fertility or is it just showing me I'm doing my log?
