Which day did I ovulate?

Ch

Thursday-Friday (3/8-3/9) I had positive OPK tests. Saturday morning I would say it was negative - the line was still dark but not the same as the control like the prior 2 days.

Which day would you say I ovulated? I would guess Saturday (3/10) since that's the first negative after the positives but not sure? 🤷🏼‍♀️
