Positive OPK last week and now today?!??

I am soooo confused 😭 I got a Positive opk on Thursday 6/28 which was predicted to be my Ovulation Day. We baby danced and Now I was doing the 2 week wait, expecting Aunt Flow on 7/10.

This is my 1st Month using OPKs so I took a random one today so I could use it to compare lines but holy cow it's definitely POSITIVE. How is that possible????

When I got my 1st Positive it only lasted about 12 hours and then I was getting Negatives again.

And is it even possible for me to Ovulate only a week before my expected period??

I took a pregnancy test and it was Negative, since I read you can get false opk positives if you're pregnant.
