Should there be a certain reason for the cramps?
Hi!
It isn't too uncommon for women to skip a period now and then. It is a little less common to skip two, but it is possible that using Plan B has affected your cycles. If you were my patient, I would recommend that you come in and that we start some form of birth control for you--it can regulate your cycles and (obviously) prevent unwanted pregnancy as well.
By the way, I hope you are using condoms and have had your Gardasil series! Sorry for the nagging!
Good luck!

Oh and I also get a lot of cramps but no period
