My doctor has suggested I have the mirena fitted to combat severe pmt, but I'm very nervous about using hormonal contraception as I tried several different types of contraceptive pill when I was younger and all of them effected my mental health to varying degrees, the last one being cerazette which I took for a few months in 2008 and which gave me such bad depression that I was nearly suicidal at one point... I also don't feel my mental state has been quite right ever since 
However, if a hormonal iud did work to prevent me from getting severe pmt symptoms it would transform my life!
I'm scared to try it though in case the hormones in it had a negative effect again. I've just had a baby so really couldn't cope if it had a detrimental effect on my mental state.
Any experiences would be really appreciated, especially from anyone who's previously had issues with the pill and gone on to have success with the hormonal iud.
If I don't get the hormonal iud I'll be having the copper coil again, which I had before and got on fine with.
