I’m lost

This app is full of information but as someone that isn’t so tech savvy I’m having the hardest time navigating it and utilizing all the premium tools. I need help.

I got off my birth control 7 months ago (which I’ve been on for 15 years) and I’m still experiencing extremely irregular periods making it so hard to track ovulation. On top of that my periods are virtually undetectable because I don’t bleed on them nor do I experience major bloating or soreness. I’m struggling to even detect when I’m on my period. I feel like I’m failing at all this.
