HOW CAN I STOP IUD SPOTTING FOR A FEW HOURS

I need to stop bleeding for a few hours and I really need tips on how to. I don't heavily bleed, but it shows up on a liner and it comes on a schedule. I know you can't stop it but how do you lighten it to the point where it's barely noticeable. I'm really not tryna get into it and have a real life Carrie scene happen...
