I had posted a post a few months ago about how I had weird spotting but no period. Well, it has now been 4 months since I've had my period. I am almost 16 and used to have fairly regular periods before going veg (I eat an almost vegan diet). I am definately not pregnant (I'm a virgin).I went to the doctor a few months ago, who put me on lots of supplements and told me to eat more fats and protein. I am doing that but it's not working. Otherwise I'm pretty healthy. I'm thin, but healthy thin. I weigh about the same as I did prior to being a vegetarian. I've heard that soy can throw off the cycle so I've cut back on unfermented soy. In general I eat a healthy diet so I don't get why I've lost my period. It's starting to really alarm me. I may start to eat eggs or dairy everyday, because as much as I love animals, this can't be good for my health. The doctor thinks that I may have PCOS because of my irregular periods and also my mom has this syndrome. Do you think that a vegan diet is related to losing periods?
