"i am 23 and had my first child on may 27 2011. at my 7 week checkup i had mirena put in. the procedure was uncomfortable but bearable. a week later i started my period and it lasted two weeks and was painful and heavy. i also got a bacterial infection in my uterus due to mirena and was on antibiotics for 7 days. i had nonstop cramping, nausea, bloating, back pain and spotting along with a weird clear discharge, slight memory loss and painful sex in certain positions. after 3 weeks of this i called my doctor and she put me on the pill.
