Is it really worth using OPKs or does it just leave you obsessive & paranoid?

Is it really worth using OPKs or does it just leave you obsessive? My husband and I got pregnant twice although the recent pregnancy was a loss without any tracking at all. I have started using this app and 2 cycles so far I am tracking and I didn't seem to ever get any positive OPKs, they are high solids but not quite positive. I am probably missing the peak. But my husband has said that I sound obsessive and it's turned him right off so just like that the fertile window has now gone. We only DTD & BD twice. And I have no hope. This is making me really sad today. I can't stop crying. Maybe this is why they say stop thinking about TTC? I feel OPKs ruin everything.
