"just got my skyla this morning. i took 400mg of ibuprofen before the insertion. the entire process was about 5 minutes. i would say the cramping during insertion was way worse than bad period cramps but only lasted like 30 seconds! i felt a tiny bit light headed immediately after, went away by the time they told me to get dressed. after reading these reviews i was worried about having to go into work but i was fine! 2 more ibuprofen and i was good all day! very light bleeding, just needed a liner. if everything goes as smoothly as the insertion i&#039;m gonna love skyla."
