Confused about ovulation test

Sh

So I ovulated on Tuesday. I had an extremely obvious positive. On Wednesday I took another one just to see how the line progressed and it was barely even there. But for some reason today I had a cramp in my left side and idk for some reason I wanted to take another one AND I KNOW ITS TOO EARLY TO TAKE A PREGNANCY TEST BUT I COULDNT HELP IT anyways my ovulation test came out pretty dark when I expected nothing to be there. Any one have this happen to them? I’m just confused
