Advice and feedback sought.. I'm thinking of having a coil fitted but am loathe to have the copper coil as I know it can make periods heavier and more painful and mine are just terrible already! But having been on the pill for years when I was younger (microgynon) and felt horrible mood swings / depression / pretty darn mental a lot of the time plus weight gain, I'm also loathe to try anything with hormones. The GP said that because the hormones are localised with the Mirena, it doesn't effect women in the same way as the pill and the chances of hormone related side effects are extremely small but have had a quick google and some women do seem to find it makes them feel dreadfully hormonal and down, big weight gain too. What are people's experiences with the Mirena coil? Do PM me if you don't fancy replying on this thread, thanks!
