Paragard

So I’ve had the paragard iud for almost a year and with it comes extreme cramping to where I want to drop to the floor and my periods are so heavy I bleed through super tampons in less than an hour I’ve resorted to wearing a pad during this time but I was wondering if other females are experiencing a lot of discharge accompanied by a strong metal smell coming from your vagina constantly it kind of makes me embarrassed to want to have sex because of the smell
