My gynaecologist has recommended that I have the mirena coil, to help combat severe PMT which is getting worse, and makes me a horrid cow. I'm happy to give it a try, but have read nothing good about it on here - all the posts I can find refer to horrendous weight gain (really don't need that, thanks,) and PMT (?!). Has anyone had a good experience of it? The (lady gynaecologist reckons it's the best thing to happen in the field of gynaecology!
