First time using OPK

Hey ladies so it's my first cycle tracking ovulation. I bought a dollar tree test yesterday an tested at 2:30 on CD 14 an then I tested today at 2:30. Today I'm on CD 15 an it seems like I'm almost there. Just wanted to know if you ladies think I could be ovulating today or in the next couple of days. Glow says I'm at peak today. Google says because I have a 30 day cycle I'm at peak this Saturday.
