I have had awful cramps for years - to the point of throwing up from the pain.  I started using a menstrual cup at the beginning of the year and now I need to pay attention to my cycle and start using the cup a few days leading up to it because now I have NO WARNING!  No cramps, stomach problems... I don't even feel bitchy beforehand anymore.  Is it possible that somehow tampons worsen PMS symptoms?  Anyone have any similar experiences??  Just curious!!
