First timer with OPK's

Kasara
I have never taken an OPK before until this past month. I had my sycle twice which was odd but it had been 6 months. The DR wasn't sure why. Do I don't know which sycle to go off of for the kits. I had started testing on the day 7 after the first one because that's what my Gyno wanted. Glow says I'm not supposed to ovulate for another 2 weeks almost right now. What do you think? Is it work taking another test later today?
