"so let me just start out by saying i have had skyla for 3 years now and i never got pregnant so that&#039;s a plus . 1. insertion is painful but just like a really bad cramp last only a couple of seconds . 2. post insertion i had a lot of spotting for the first 2 weeks got a little annoying , but stopped . 3. for the past 3 years i have been having irregular periods sometimes i have my period for 2 weeks , sometimes there is no period . i feel very painful cramps during these periods but if u don&#039;t want to get pregnant what&#039;s a couple of cramps ? . pros .... very effective birth control , easy ,sometimes no periods , no acne ( depends on the person i guess ) . cons .... lost of sexual appetite , increase in discharge ,weight gain . its ok ."
