I'm guessing this has been discussed time and again,but I can't find anything good about it so thought was worth putting it out there again?! Has anyone out there had a GOOD experience of the coil??! I'm having peri menopausal problems,haemorrhaged and ended up on norestherone,I have to come off them and have been told by gynaecologist and doc that the coil is the best way to go 'it works perfectly for 80 per cent of women' I can't find one of those 80 per cent. Any experiences much appreciated
