Copper
"Only reason I am giving it a 2 is because it is very effective birth control. Otherwise I would give it a 1. I have tried 5 different B.C. pills in an attempt to control my cramps. They either worked for a while then didn't, or the hormones made me either crazy depressed or moody. So I went non hormonal, got the copper IUD, And I don't know if my body is the type of body that just doesn't accept things that just aren't naturally supposed to be there but I've done a lot of research and I'm fairly certain I've got copper toxicity because of it. So many bad symptoms please do research and if you have the symptoms get it taken out. I'm pretty sure I'm getting mine out the symptoms just aren't worth it. They're affecting my health and happiness"
