"i had my first mirena when i was 22, now i&#039;m 32 and working on getting my third one. i have never had children and i don&#039;t want to have any at all. both insertions were very painful. the first time around, i was spotting and cramping for 4 months. i hated it to the point i wanted it removed, but decided to wait a little longer. i&#039;m glad i kept it! 4 months later, my periods are so light and almost nonexistent. yes, my acne got worse, but it was because it got better when i was on the pill. i think my acne just went back to its pre-birth control levels. no mood swings, no more cramping, great birth control (10 years and not a single pregnancy or even a scare!) i recommend it, but i always say give it at least 4 months if you hate it."
