iud pain and sex

So i gotten the kyleena iud about a week, week and a half ago.

Me and my boyfriend had sex last night and now i’m having some pretty bad cramping:/

im really paranoid abt my iud moving and killing me or something. But is it normal to cramp like this?

Im curious on actual people’s responses instead of just googling it. Google will make me thing i’m internally bleeding or something:/
