Period is late!

Help! So I’m getting married in 10 days and my period is late! Now, there’s no chance of me being pregnant lol because We’ve been abstinent until marriage. I am however worried that it will come later and still be on it for my wedding day. (I got the copper IUD and it has made my periods last about 6-7 days now)

Is there anything I can do to bring it quicker? Besides being less stressed about it lol but also, if I did get it later, is there any way to stop it? I’ve heard of lemon juice but I wanna know other ideas!

Thanks in advance!
