"i&#039;ve had skyla in for about a year now, and it is by far my favorite form of birth control. some background info, i&#039;m 19 and have never had kids. other birth controls affected my mood greatly, and skyla has not affected my mood in the slightest. i also did not experience any weight gain. the only downside is my period is longer than it was before (10 days, but not heavy) and i experience cramping, but nothing midol can&#039;t fix. i can&#039;t even remember the pain from the insertion process now (which i got while not on my period), but that slight discomfort for a couple days it worth it for the next 3 years of birth control."
