Ovulating again?

Britney

Hi all.

So according to my opk’s I ovulated 8 days ago, on or around July 21. I’ve had cramps and back pain everyday since 2dpo, so Today I decided to take an opk test. It came up positive 3 different times. How could I be ovulating again? Is it possible to ovulate 2 times in one cycle 8/9 days apart? Has anyone experienced this? Thanks!!!
