"the insertion does hurt but it&#039;s tolerable. i&#039;m glad i didn&#039;t read these reviews beforehand because i would&#039;ve been super freaked out! i got my skyla inserted about 4 days ago and the worst part was after the insertion because i got some pretty painful cramps. they went away after about 5 hours and haven&#039;t came back. i&#039;m still spotting a little bit but nothing too bad. if you&#039;re reading these reviews just remember everyone&#039;s body reacts differently to birth control."
