Help me figure this out!

Okay help!!! I️ have a 28 day cycle, almost ALWAYS exactly on time. I️ should ovulate on day 14, right? Well the app told me Saturday was ovulation (day 14) but I️ had very little CM. My first response sticks showed what I️ thought was a positive ovulation (fairly dark, pretty much matched test line) Well today I️ started cramping and I’m having egg white CM. I️ just tested and the bottom strip was just now! Top was last night... what do you guys think? Trust my body and test? Does this mean I️ am ovulating now??
