what's going on? TMI pictures

This started last night. I was 9-10 dpo, 5-6 away from af. This is still going on today. But it's not enough to wear a pad. I've had slight on and off cramping, some lower abdomen pain/cramping. I'm extermely tired today don't know if it's because I was busy yesterday or what. Everything I look up seems like all the signs of implantation. But I'm really trying to not sike myself out and get my hopes up. I just think it's odd. And don't know if it's normal or something I should be concerned about. Or what the heck is going on. Has anyone else experienced this and it's just AF coming, it was implantation, or something else?
