Opinions on opk!!!

Here’s what my cycle looks like. Says I’m supposed to ovulate the 28th but I haven’t actually pinned it down to the exact day!

Is there ANY way I could have ovulated on Wednesday!?! My line is not as dark as the other I realize that. But I’ve seen a lot of women say that it can be slightly “not as dark as the other line” I plan on keep testing! Would love some opinions, thank you.

Plus I had the weirdest feelings like tingles, not painful cramps, twinges, in my left lower side and kinda the right.
