OPK progression?

Stephanie

This is the first cycle testing for ovulation- weve tried for 3mo and no BFP and was wondering if I'm ovulating way off from what the app suggests based on my 29day cycle. I usually see other ppls progressions get darker--- mine seems up and down. Is that normal? Did I peak on CD7?! Please help. (I'm taking 2 brands at the same time)
