"i got the iud a little over two months ago after searching forever for a birth control that has good side affects and doesn&#039;t make you gain weight. i haven&#039;t gained a single pound from being on it. my periods are have still come but they are super light and last about 3 days, they are also sporadic but i don&#039;t blame it too much since before my periods used to last 7 days and were sporadic anyways.i have little to no cramping and when i do cramp it lasts about 3 days and usually the 3 days i lightly bleed. also every now and then i check for the strings and they are always there in place. the reason i am giving it 9/10 is because how many stories i hear about having to have surgery and it makes me stress about what if."
