Possible implantation cramping?

I am currently at 10dpo. Tested this morning and got a bfn.

Since 8dpo I have gotten on and off cramping on my right side. It's mild, but feels a little like a sharp pinch that comes and goes. It doesn't feel achey or intense like my period cramps usually do.

It's also a little bit too early for me to be having period cramps (I tend to have them start around 12dpo).

Could this be implantation cramping?
