Mirena
"My sister and I both got the Mirena, she still has hers and loves it, my experience was not great. Insertion was brutal and my belly looked about 5 months pregnant for the next week, if I bumped my belly it hurt like hell. I never got my period on it but had constant spotting for 9 months as well as serious mood swings. Eventually I got it taken out because my body wouldn't adjust to it."
