birth control
"Gained 60 pounds in less than 3 months, periods went from 28 day-4.5 day clockwork-regular to 2X a month, 9 day long  murder-scene heavy.  PMS used to be mild to nonexistent, went to migraines from hell, debilitating cramps, etc.  Dr. told me to stick with it.  I did for a year.  Off the ring, took a year and lots of work to get my periods back to something approximating normal and the weight will NOT budge.  I did not have weight issues before, never had.  Now I also have endometrial hyperplasia and have been told the weight is sticking no matter what I do to lose it due to an overabundance of estrogen.  If you use the Ring and start gaining or going period-wonky AT ALL, stop, please, immediately and do not be like me."
