"i got the skyla iud inserted in march 2015. no pain what so ever just felt like period cramps nothing to cry about. but then again i&#039;ve had 3 vaginal deliveries so guess i can&#039;t feel pain.  so far with skyla my hair is falling out,mood swings, weight gain. i been reading around on skyla because i&#039;m getting scared reading everything about mirena . everyone&#039;s body is different.  so far it&#039;s worked for me."
