just a thought a few years ago i wa s refered to be steralised because i was having very heavy periods, but as i was over weight Gynaecologist would not do the procedure but he came up with a very good alternite option, as i was allready using a coil he sugested one which would give of hormones and eventually i wouldnt see a period , with having four children , and family histroy of heart problems and also being anemic this new coil he said would take me up to my menapouse, that was 2003 and it should be ok untill 2008 the name of this coil is MIRENA it might be called something else in the us, i have had no problems, i found this website hope this helps, http://www.mirena.com/html/index.html
