Help! I’m so confused!

So per my bbt graph it looks like I ovulated on November 20. I used an opk and it said it was just a high chance (it was a digital from Clearblue). Kept taking test and my husband and I TTC during that window. Fast forward to last Friday, November 30th. I was at work and felt off... realized I hadn’t went to the bathroom in a while so I peed and when I wiped I had some of the sticky egg white CM. My husband and I TTC that night before he left for National Guard drill. Realized 4 hours later I should take a opk just to see. It was PEAK. When I looked at the actual surge when I took out the stick from the digital reader it was a huge surge. Has anyone else experienced this?! When did I actually ovulate?!
