Is it possible? Ovulation

Is it possible that I ovulate on the same day that I get my positive opk? Everyone says that you’ll ovulate after you get your positive, and glow logs it as the next day, too. But, I think I may ovulate the day of my positive opk, and here’s why:

-I get ovulation cramping, it’s one-sided twinges or sharp pains, I’ve had these for many years. And it’s always the day of my peak opk.

-I get ovulation spotting, not every cycle but the majority, and it’s always the day of peak opk, if it happens.

-I always get heeavvy EWCM day of positive opk.

-and finally, I get dizzy spells day of peak opk.

So, I really feel like I am ovulating when I get my positive opk, but is that even possible? My OPKs are usually kinda high leading up to ovulation, and then once I get a positive, it drops off to very very negative, almost white the next day, which would be “ovulation day” according to glow. Thoughts?
