"i am 22 years old and have had my mirena for 13 months now. mirena is care free, but popping a pill once a day is not that much of a chore either; which is why i&#039;m going back to oral contraception. after insertion i experienced constant discharge and bleeding for 2 months. now, i don&#039;t have bleeding at all, only spotting for about 2 days per month. the shortened periods are not worth it for me. i get serious stomach cramps and migraines before each period now. i used to experience only mild mood swings. there&#039;s also dizziness, depression, irritability, insomnia and a very low sex drive (odd for a 22yr old). i want to get back to how i was before the mirena, this is not the birth control for me."
