Hmm, there are a number of reasons why there is no period. One could be the lack of a nutritional diet, high in vitamins & minerals. Another major one would be a highly toxic body--full of different pollutions & crud that can be picked up from our environment, foods, and drinks. I would try to began switching to a more natural, organic diet--find an all-natural vitamin/mineral supplement & began taking as directed. Drink 8(8oz) glasses of water a day or 1/2 amount of body weight in ounces of water. Find a holisitic gynecologist (could help recommend different natural treatments & plan of action--could also recommend several other tests--blood composition and such) I don't really have an exact idea of the problem--anyone else have an idea???
