"insertion was virtually painless. i&#039;ve had it for almost 5 months and i hardly notice it. no weight gain or loss (i was really hoping to gain weight from it since i&#039;m very skinny). i&#039;d assume the people complaining of weight gain probably produce a lot of eestrogen in general - but i&#039;m not a doctor so don&#039;t take my word for it. no mood swings,  no headaches. i still get my period somewhat regularly,  however it&#039;s longer by a week or two but lighter. i hardly notice it, my period symptoms have also lightened up a bit (less pimples, less cramps, less attitude). i would recommend this to anyone."
