Got my period twice this month first time within a week, I have cramping my breasts hurt pretty and bad stomach cramps. First time happened?

I have a few questio. First, I have to ask if you have been sexually active? If you have, then this is probably an early termination of a fertile egg. There are other possibilities but I think that the most likely is what I stated above. If you have not been sexually active, I would suggest an appointment with your PCP.
