I also have not have my period since being 100% raw, a little over 5 months . If you feel healthy and are still ovulating that this is a good sign that your body is clean or getting clean. If you are not ovulating than you could be malnourished and I would suggest you eat more greens. You will know that your ovulating if you notice a little white discharge when you wipe around the time before you might have your period. Another reason your not having your period could simply be the big change in diet and it might resume when the body has adjusted to the changes. Also, when your breastfeeding, especially if your doing it exclusively, it is normal not to have your period, and it should resume when you stop. I feel fantastic and know that I am still ovulating so I don't worry about it. Good Luck
