Cramping?

This is my first cycle since stopping bcp in October. Af was from 2/1-2/7 and according to this app I was supposed to ovulate on 2/27. (Purchased opk for next cycle, as this is my first cycle and I wasn’t too sure I would ovulate.)

I’ve been having this cm since 2/26:

The picture below is from today:

I baby-danced twice this cycle. Once on 2/25 and once on 2/28. Now I am cramping. Not bad but persistent. I’m not sure if I’m just now ovulating or should I be preparing for af. What do you guys think?
