2 positive opks 2 days apart?

Friday evening, I got a positive opk(posted the pic on a thread). Yesterday afternoon(Monday) I got a negative opk but then checked again later in the evening and it was a positive. Sooo what do you guys think is going on? I'm so confused.

This has happened to me before, maybe u geared up to ovulate but didn't. Do u always test at same time of day?

Yea I figured it was that because I had taken another test the next day and it was super positive. I test at 10pm. It's easier for me at that time because during the day I'm busy.
