"after 2 children, i have currently had mirena in for 13 months. here is my last 13 months: mild cramping with insertion. spotting continuously for 4 months straight. strings sharp and poked my husband. 1st period was heavy. continued spotting. headaches. complexion getting worse. unusual hair growth. mood swings. fatigue. unable to lose the baby weight. i finally stopped spotting at around 10-11 months after mirena was put in. i now continue to have periods every other month that are mod-heavy. also noticed a sour smell to my vagina. i feel like i am always moist and have suffered from yeast infections. on a good note it is low maintenance and i have not gotten pregnant. strings also have softened."
