Implantation cramps?

So the night of 5/20 I started feeling small tiny like cramps. They felt specific to one area. Anyways, they were off and on all day yesterday. I wouldn't say it really hurt at all, just a strange feeling.

They probably arent even implantation cramps and it's just wishful thinking, but if you did have implantation cramps, how long after that did you get a bfp?

I was 11 dpo yesterday when I had the cramping. Bfn this morning at 12 dpo. Trying to stay positive, but losing hope.
