OVULATION HELP

Chloe

Okay, long post sorry.

I know these photos say CD 1, but I haven't bleed at all.

Anyway, I thought I had my peak of CD 18, that's what the app said, my levels went back down low so I stopped testing, today I've had cramps. Tested again (I'm not on CD 37... and it's blazing peak.. anyone else ovulate so late?? Does this mean ovulation failed heaps prior to today?..
