Ovulation drop

Emperial

This is my chart . My opk last night was really light and actually lighter than the one before . I have a donor so I usually travel when I’m due to ovulate . I will take an opk in a few hours but wondering if I should go ahead and make the drive with this big drop . And I know it’s a true drop because I forgot to turn my air back on after my shower so I was actually kind of hot when I woke up .
