First month of OPK

This is my first month of OPK testing. Looking back I should have taken better photos for my log. I know I had my positive on CD13, my reader kept telling me today’s test was positive? I know everyone’s cycles are different just a little confusing if a high test is normal still? I have a normal cycle of 26/28 days.

My work schedule doesn’t allow me to test at the same times unfortunately.
