Which is best?

I recently stopped taking the pill, because I could never remember to take it anyway. I felt that was probably not doing my hormones good since I was back and forth with it. I don’t feel comfortable in getting an implant Bc of all the things that could go wrong. Is it completely stupid to use tracking my ovulation as birth control. I do not want to get pregnant right now as I am in school. But I also don’t want to ruin my future chances at getting pregnant so I feel it is best to use a natural birth control method such as <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a>. Opinions??
