Continued negative OPK

Katelin
I just moved into a house a couple weeks ago, right when my period was ending. I planned on testing everyday as soon as I stopped bleeding, buuuuut, I misplaced my tests. 😔. I found them on Friday! (July 31) and have started testing then. That would've been CD 14 for me. And been testing ever since. I'm in my 'projected fertile window' according to glow. Could I have completely missed my ovulation? I made sure to BD as much as possible. Especially without knowing if I was ovulating or not.
Does anybody else have issues finding a positive OPK
