Super confused! Second positive OpK after clear positives?

Color me confused! Thursday and Friday I had CLEAR obvious positives, test line darker than the control. Thursdays was even darker. This also lined up perfect with glows predicted ovulation day for me. Saturday morning was negative but still really dark, later in the day a lighter negative. Yes Now today it's another positive! Not darker but the same as the control line. Photos in the comments including my temp charts... so confused.
