"i got mirena put in feb 2013, and now having for 8 months. i was never on any kind of birth control before, and i have one child. i had it put in at the time of period, which my ob/gyn preferred. during insertion, the pain was horrible and i had cramps the rest of the day. i spotted for about 3 1/2 months straight. this last month i have really noticed that i haven&#039;t had a period, i had some spotting for about 3 days. i&#039;m guessing its tapering off. i haven&#039;t had any abnormal acne or mood swings. i do feel like i&#039;m more sexually active."
