birth control
"I have been on Mirena for 4 years now. It has been good so far, I have not had a period or spotting in almost 4 years. I haven't gained any weight (but I do feel bloated from time to time). The only down side is my sex drive has nose dived. I used to ALWAYS be ready to go another round but now I have no interest which causes me to get a little moody but the positive out weighs the negative."
