Implantation cramps?

I have been getting crazy cramps all day that feel exactly like period cramps, but I'm due for another 2 weeks. I just ended my fertility window 3 days ago and still have not pin pointed my actual ovulation day. It seems a bit early, but after 5 months of trying with no luck, I still seem to be getting my hopes up!

Thoughts anyone? Could this actually be implantation cramps?
