Is it normal to have a weird smell coming from your vagina? READ DESCRIPTION

Ok so it's been going on for a while now but just at the most random times I will smell this foul smell and it's coming from me and it's coming from down there. And it doesn't smell like the same smell of a period. I shower regularly and haven't changed anything that I have been doing for a while. It's REALLY embrassing too. Oh and I have an IUD as well. But it's been in for almost three years now. I started using those feminine wipes and those don't even help! Someone please help me!
