Am I implantation cramping?

So, I've been ttc and read that implantation cramping usually happens 6-12 days after ovulation. 
I'm 9 DPO and my lower right pelvic area kinda aches, not really a cramp. 
It feels like I've been overworking my waist area, but I haven't. That's the best way to describe it. 
Could this be implantation cramping?
