Do you have to pay to track your period on this app now??

Hi. I’ve been using this app for at least 4 or 5 years now. I used to track my period when I stopped using birth control. Then I got pregnant twice and now have a 3 and 1 year old. I’ve been pregnant and or breast feeding for 3 years straight so I’ve only had two periods in the past 4 ish years. So I had my first period (my baby turned 13 months old) and it’s coming to an end but I wanted to add it to my GLO app but I can’t. Do you have to pay for that now??? Wild to have to pay for something so simple.
