When I had the Kyleena IUS inserted it was incredibly painful, I had debilitating cramps that lasted around 8-10 hours after the procedure. My first bleed was very heavy and lasted for almost 2 weeks, the next one was lighter and by the third I had lost my periods. Once every few months I would have pains so bad that it felt like someone was stabbing me in my abdomen and I could not move, not even painkillers would relieve this. I felt like my sex drive was completely killed, if I did try any kind of penetration I had that same cramping and ocassionally I bled after sex.

My sex drive returned to normal when I swapped to the nexplanon implant, the cramping stopped completely and my skin cleared up.
