Copper coil

Does anyone else experience extrutiaring cramps when on their period? I've got the copper coil and I really enjoy having it, that is until I start my period and I am faced with pains beyond belief!!! The pains are so bad I even consider having it removed! I know the cramps are meant to be worse but I've had it in for ten month now and they are not settling down. Before the coil I was on    for 5 years and my periods stopped completely. It would be nice to know of anyone out there that feels the pain! Hah!
