is this right?

so i took an OPK July 17 @like 11 pm and mother one July 18th at 12am and the test line was DARK both times.

I got my period August 1st, was spotting for like a day and a half before.

Would that mean that my OPK was correct and I did ovulate one of those days.

Or when do you get your period after a positive OPK or positive BBT? (i know they are two different things and just bc you get a positive opk doesn’t mean it’s true) but since i didn’t get my period 2 weeks later, that would mean that my OPK was right?
