OPK question


Hello! Okay..so I just recieved my very first package of OPKs in the mail today. I've never used them before, so this test is the very first one I've ever done. Im confused because I don't have anything to go off of, and I also don't have prior tests to determine what my "normal" would be and when i would have a "surge". But this test looks like a peak test. Im on CD12 so im getting close to ovulation. Would you consider this a peak even without having prior tests?
