"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&#039;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&#039;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."
