Unable to wear menstral cup due to copper coil and symtoms

Update

I had it out in September 2 years ago my spots went within weeks Ive since lost 4 stone my mental health is soo much better I don't have brain fog or low motivation.... If u think your coil is giving you symptoms it is people made me feel like I was insane and it's not hormonal etc guess what look up copper toxicity then come back to me

Is anyone else not able to use a menstral cup after having iud I have the copper one

Also side not anyone put on about 3 stone (or any weight) on this coil

Also feel tired 24/7 and really poorly all the time I've had it in since April 19 so I thought things would settle can anyone relate?
