AF style cramps but at least 8days from period?

Has anyone had this at all and ended up with a BFP? I've been cramping on and off for a couple of days now but tonight it really feels like af. If it's af it would be at least 8 days early, as I am only on cd23 of 32 - I never get cramps this far ahead. Had no bleeding or spotting whatsoever. I am currently 7dpo, any help or advice you lovelies?
