Kyleena IUD

Ca

So I got my Kyleena IUD on the 21st of January(so basically a week ago) and I have had like pangs of pain where I sometimes have to stop what I’m doing and breathe thru it. The pangs of pain feel like really bad cramps that also sometimes put pressure on my crotch and behind.

But today I now have some really dark brown discharge and a funky smell? Is this normal?
