OPK help

Brianne

New to OPK test strips. According to glow I should be ovulating this week. I use Premom to track OPK test results. According to the test I peaked this afternoon but my line really isn’t darker so I am confused and now the line is really light again.Did I peak or is that just high? I am suppose to go in for a progesterone test on day 21 if I haven’t seen a positive ovulation test so trying to figure out if I have or not. Any help is appreciated. Ready to ovulate and make a baby!! (:
