"i&#039;ve had the skyla iud for 2yrs now and it&#039;s been a fantastic experience. i will admit the insertion was very painful. i took 600mg of advil about an hour beforehand and it was still very painful (an 8.5 out of 10 pain wise). the rest of the day i had to stay home because the cramps would come in waves and were severe. after 2-3 days the pain was gone, but i did have bleeding/spotting for about 1-2 months afterward. however, i was on depo provera prior to the iud and it caused my uterine lining to really thicken up, so there&#039;s no telling whether the bleeding was from the iud or from the depo. since then my periods come every 2 months or so, and only last about 3-4 days, and i&#039;ve never once worried about being pregnant. highly recommend!"
