Just want to preface this with everyone has a different body thus a different experience with an IUD. This is my case: I got an IUD September 2016 and my cramps got HORRIBLE. This is a common symptom, expected to go away in 3-6 months. However it never went away, two days out of each period I was cramping so bad I had to skip work and school. I kept pushing thinking my body would get used to it. Long story short it never did. The moment I sat up after getting the IUD removed I instantly felt more comfortable with myself. There was this tension gone from my uterus. A week later my period has started with little to no cramps and I feel sexier and myself again! If your IUD isn't working, GET THAT SHIT removed! The risk of pregnancy is so low but it isn't worth it. Listen to your body. :)
