Clear blue advanced OPK question - high in am and then peak at night!? How to mark?

Hi ladies! I have been taking clear blue advanced every morning since AF ended. I got a high (flashing smiley) on Sunday and this morning at around 8am(Monday). I just took another one out of curiosity because I see a lot of girls testing more than once. At 10:30 I got a peak fertility (solid smiley)!! We’ve BDed sat sun and this am. My question is — how do I mark it today on glow? This am was high and now just before midnight it’s peak!? It impacts my

Ovulation day on glow so trying to be accurate! Will keep BDing this week anyway, but mostly curious for purposes of figuring out ovulation!! Thank you!
