"i have had skyla for over a year. the insertion was not as bad as i was expecting, however, i had a child a month prior. the only complaints that i have are the terrible acne and the difficulty i have had losing weight. i have not gained any weight, however, i have had a hard time losing the weight that i wanted to (only about 10lbs). overall, the reason that this is available is for birth control. it has been extremely effective for what it was meant for."
