"i just got my kyleena iud 2 days ago so far i&#039;ve been really crampy &amp; also nauseous not only that i know they say you are not suppose to feel the iud but i swear when i bend i can feel it so idk if its just my body trying to adjust to it or what but so far i am very uncomfortable. the procedure seemed to take forever to me but so far i&#039;m gonna give it a month to see how it acts i really hope it helps with my heavy crampy periods."
