Ending birth control after 6 years

I have been on Camila (mini pill) birth control for over 6 years now and I want to go off to see how my body is without it. I struggle with weight and other side effects I believe from the birth control. How do I begin tracking my period and my ovulation days after being on it so long. Do I continue on this app and just take the pill off ? I do not want to be pregnant anytime soon, so I want to prevent that at all cost. Please help!
