Confusing OPKS

Nakita

Okay, maybe you guys can help me. Idk wtf is going on with my body. It did this last month where I got a positive OPK and failed to ovulate until later in the month & I'm just praying that's not happening again. I had a mc May 8th and nothing has been the same since. I thought I was 7/8 dpo today but idk at this point. What are y'alls thoughts ?
