Copper IUD

I had the insertion done 3 months ago. My periods are heavier, longer(10 days counting spotting), and with more painful cramping. I cramp when I ovulate now too. 
Does any one have any natural remedies to alleviate pain? I have tried chamomile,ginger,cinnamon, and peppermint tea. I heard about cramp bark tea, has anyone used this??? I don't want to take pamprin or extra strength Tylenol all day. I live in Chicago and these winters makes the pain so bad when I'm going it on a daily basis. Does the pain subside ladies???! 😰
