"had kyleena inserted 5 days ago as i decided to switch from the pill. having never been pregnant before insertion was uncomfortable for me. i felt some strong cramps during but was able to return to work as normal about half an hour later. cramping was not enjoyable the first night, and i had advil and tylenol on repeat with my hot water bottle, however i woke up the next day with no cramps and a few spots. same a few days later. time will tell what it will do to my period but overall a great experience. everyone&#039;s different though, and please don&#039;t believe every bad thing you read online. i love my kyleena and it sure beats taking the pill everyday."
