To use opks or not

I'm starting to feel the stress of TTC, and am wondering your thoughts on using opks and/or temping. We started "not preventing" the beginning of 2019, summer of 2019 we started "trying" just by using an estimated fertile window. I got pregnant last fall but miscarried. Even with many months before getting pregnant, it wasn't until after my miscarriage that I really started to feel discouraged. Do you think using opks helps you or stresses you out more? I'm trying to decide if we should keep doing what we're doing or if I should take more charge of the timing. I've always had regular cycles and know the day I conceived in the fall because we happened to only bd once due to work travels.
