A little confused? Please help.

My period is usually every 26 days and according to glow I was sopposed to begin AF on Sept 5-8th and I never did, I was late and started on September 10th and stopped on the 14th. Afterward I started opk testing at cd6 and it had a faint line, then cd7 was a little lighter, and now cd8 there is like nothing there?! I am so confused? Have I missed ovulation?
