I'm thinking of stopping SS for awhile - maybe moving to 790 or 1000 or even going on on low GI diet. Started my period nearly 3 weeks ago and it shows no signs of stopping - has this every happened to anyone? My cycle was regular - every 28 or 29 days - periods 4 - 5 days - but never been this long. I feel OK - just an achy tummy, but more concerned about such a long period. Any advice appreciated. Thanks.
