Copper Coil

Had a copper coil fitted a month ago after loosing a baby, had sex today and we both agree it feels different and think it’s moved so I’m going to schedule an appointment with the doctor to check it, but today I’ve had bad cramps and a tiny bit of spotting, I think I’m due on my period but obviously with the loss and the coil I’m guessing things have probably been thrown out of sync has anyone else ever experienced this? Don’t want to freak myself out over nothing but I’m already freaking out lol any advice would be appreciated xx
