Hello....I had the same feeling about a week and a half ago...it lasted for three days. I had never had a "cramp" (for lack of a better word) there, but the day AF was supposed due, she arrived!! I was so disappointed. I just knew that since I was feeling something different that this was my month.....
Sorry if that is not what you wanted to hear. Hope your right side cramp is something else.
