Levonorgestrel
"I wanted to try Kyleena because I have had a horrible reaction to the pill. (Weight gain, constant nausea, swollen breasts, headaches) I am 22, and have never had kids. The insertion wasn't all that bad, it hurt like absolute hell for 10 seconds, and then it was over. (I did take 800 milligrams of ibuprofen before hand) The first week, I felt great! I didn't really spot. I had very light cramping, and it was effective immediately (so worry free sex, yay!) Within the second week I unfortunately had to get it removed. I started having horrendous cramps. They were so bad I debated on going to the ER. I made an appointment with my Gyno, and turns out that the IUD shifted WAY out of place. I really sucks because I was super stoked to have this."
