Period cramping or implantation cramping?

My period hasn’t been right in two months. Every time my period is either on it’s way or here, I have SERVER cramps. But it just feels like I have to throw up and a little dull feeling in my lower abdomen. Has anyone had this feeling and ended up pregnant?
