COPPER IUD YES/NO/MAYBE SO??

Br
Here's my first question ladies. If anyone has the copper IUD i would love to hear the good, bad and the ugly. I would also like to know does it help with period heaviness or period cramps (this device came recommended by my dr due to the fact I get major cramps) of course I'm doing my own research though. 
Also do you think it's a good idea to talk to my boyfriend about the IUD and get his input. In a way it will be effecting him as well. 
Thoughts? 💭
