cramping after ovulation but way before AF...

Evelien - 💍 - 💙🩷🩵
Hello! 
I'm 3dpo and have felt slight cramping almost every day since ovulation. It's not all day long but I feel it almost every morning for a while and sometimes during the day.. if I was more dpo I'd think of implantation but it is way too early for that. And I'm really not close enough to AF for cramping... 
Any thoughts/ideas as to what might be going on?
