Help - my chart is a hot mess

I'm hoping someone can give me some advice on what's going on. I am coming back from a late pregnancy loss and have had one full cycle since and it looked like I ovulated in that first cycle but this cycle is all over the place. I was about to give up and just write it off to my hormones being messed up but then yesterday I got a peak OPK result so I felt full of hope again. This morning I was expecting to see my temp spike but it only went up a bit. Do you think there's still a chance I could ovulate or was my OPK result false? Could it be doing a slow rise? We want to conceive again so badly but this is stressing me out!
