IUD STRINGS AFTER FIRST PERIOD

Dani
Hey everyone so I just got my IUD 12/02/15 and had my period over the weekend. Now my string is super low. Like I can feel it hanging out of my vagina a little bit if I squat enough. I can't feel the tip of the IUD sticking out of my cervix or anything but I'm really concerned if this is normal. I know they move after the first period but this feels like quite a bit. However there's no cramping or anything either which I've heard is associated with it getting messed up. Should I be worried?
