"i was on the nuva ring from 18-20. i took a break from it and went on the mirena. now i am back on nuva ring and it was nothing like i had experienced the first time. crazy pms. tender breasts, weight gain, mood swings where i don&#039;t even recognize myself. i don&#039;t know why i all of the sudden am having negative side affects with this medication when i didn&#039;t before. the only plus is, my periods are really lighter. but honestly, i think i&#039;m done with it. worst birth control experience i&#039;ve had. not a fan of the crazy."
