Hi A.,
It is completely normal to have cramping with no period. Your body is just going through the motions. Even though you aren't bleeding.. to your body you are still having a period. So it will do everything else you normally have during a period but without the bleeding. I did the same thing when I breastfeeding my daughter. I would get hungry, get bloated and all. Plus it could also be your uterus contracting back to it's normal size and all. Unless it gets to be painful or begins to not feel like your normal cramping feeling I would see a Dr. But for now you are fine. Good luck with the breastfeeding. It is the best thing ever.
