Do I need to pay for this?

I’m not trying to get pregnant if anything avoiding it Lol but I use this app to check my periods and also to see what chance % I have of becoming pregnant if I was to have sex on certain days on the calendar, it used to tell me for everyday I clicked on what % it was whether it was 3% on a day I wasn’t ovulating or like 20% if I was , I don’t get on with birth control so only use condoms, has this feature been removed or moved to somewhere else on the app or is it something I have to pay premium for now to see? I don’t use this often I just find it interesting to see. Please let me know thank you!
