IUD Copper

A • Here to track my period🤘🏼

So I have the IUD I’ve had it for about 7months i believe and everything was going good until last month I forgot to check my string and recently I’ve been trying to check it and I can’t find it, I’ve also had really bad stomach pains and feel nauseous and like throwing up, I haven’t gotten my period either and I’m already late😥 what should I do? I already made an appointment with my dr but it’s in a month
