Wtf is going on with my body?!

So, I'm suppose to be ovulating tomorrow or the next day. I'm temping and using ovulation tests every morning. I got almost a positive opk the other day and now they're just getting lighter and lighter. My temp is strange too. At first I wasn't doing it right but now I am and it's still weird. Anyone know what could be going on or have anything like this before?

Temps:

The almost positive test I had right next to a completely negative clear blue I took with the same urine.

My test a few days ago
