"i had skyla inserted a little over a year ago. the insertion itself wasn&#039;t too painful, but i did have bad cramps for the rest of the day after insertion. however, i no longer get cramps with each period. my periods are way lighter than they were pre-iud. the one thing i&#039;ve noticed that i don&#039;t like is that i&#039;ll think my period is over, but a couple days later it&#039;ll sneak attack and come back out of nowhere (though so light that i only need a thin pantyliner). i&#039;ve gained about 8lbs since i had skyla put in, but also have a job change where i went from walking all day to a desk job so i don&#039;t know if there is a direct correlation, just thought i&#039;d mention."
