iud came out of place?

so i got the iud put in on the 9th and i’m 17 and i’ve had really bad cramps periodically since then but today i went to check the strings and one was almost at the entrance of my vagina, and if i stick my finger all the way in to where the end of the strings used to be and i felt the bottom of the iud. i’m going tomorrow to check if it is out of place for sure. i’m just posting to let people know to not ignore the symptoms incase they think they’re overreacting like i did.
