Cycle day 46.

Okay so im on cycle day 46. My last af was August 10. Im usually about 31-34 days. I ovulated on the 1st or so of September. Now i know these are not good indicators of pregnancy but i was curious. My reference line is the line by the ring. And the test line is opposite. Why would i have a blazing positive opk in this late stage of the luteal phase. My test pregnancy test two days ago was neg. Thanks for insight.
