Cramping during ovulation

This month I had a lot of cramping during my ovulation week, starting about 2 days before I got my positive opk lasting until about 2 days after the positive opk... I don't usually have cramping during my fertile week, so my question is had anyone experienced this then conceived then got there bfp? It's probably a long shot but I'm trying to stay hopeful.

Here's my chart, and I got my positive opk on the morning of the 29th.

Keeping my fingers crossed. And TIA for any input. :)
