Contraception Dilemma

[Reallywantgherkins]

I currently have the copper coil and most of the time I love it! However, the random cramping is really beginning to get to me, at times it's not even cramping it feels like there's a gremlin or something scratching at my womb!!
I'm thinking of going back to the pill, the problem is, the pill really affects my mood! I've been on microgynon, Yasmin, one beginning with N and I've tried the mirena, all affected my moods (even the mirena coil) can anyone offer me any advice?
Or should I just stick with the coil and accept the pain?
