Really bad cramping?

If the pain is THAT bad you should try your hardest to get a doctors appointment, and if you can't find an emergency center. It sounds as though you may be suffering from ovarian cyst. Again, it may be something simple or possibly something serious. You need to see a medical professional. That type of cramping is usually a warning sign. You might want to ask for birth control to regulate it, and for pain management of your period symptoms.
