AF like cramps?

Paige

Ok I am currently 6dpo and I'm having cramps that feel like the cramps I get a day or two before AF shows up. But I'm not expecting AF for another ten days. These cramps started yesterday but are getting more painful and noticeable today. They are t unbearable but I definitely notice them enough to hold my stomach. What could this be? Implantation cramps wouldn't be happening this early would it?
