"i have been on skyla since dec. 12 2014. so just over a month. (no kids). getting it put in felt like really bad cramp with a lot of pressure. they insert the stick and measurer you first. (10 seconds.) they then put the stick in again and put in skyla (10sec). i was dizzy and felt sick for a few minutes. it passed. i had cramps for a day and a half. then i felt great. i was on my period when i had it inserted. they say the cervix is softer and the process will be less painful.  overall it has been great. no major cravings. my appetite has decreased since i have been off my last birth control (pill.) i cramp once in a while. my first period was longer. i would recommend! migraine 90% gone! my complexion on birth control is great! including skyla."
