Implantation pain??

I am about 6 or 7 DPO. Today I had almost sharp-like stabbing pains in waves about two inches below my belly button and slightly to the right. It was enough pain to stop my in my tracks and really notice but not enough to make me dysfunctional. The pain lasted about 20 minutes on and off. I haven’t had any pain since.

Has anyone experienced this? Could it be implantation pain?

Thank you!
