Ovulation Test

So I have a question for everyone. I'm in the green window on my glow app, so yesterday morning I did an opk. I got just a plain circle, meaning no surge whatsoever. I woke up this morning did it again, got just solid "non flashing" face, meaning, I'm ovulating within next 24-48 hours. So, question is, is it possible to go from no peek to ovulating. Or is it possible that I just poas too much. This is only my second time using opk but I wouldnt think it would just go straight to peak. Any help would be much appreciated.
