"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."
