Im 16, and i am about 5stone. I've had my period for nearly two months and the reason why i mentioned my weight is because by reading at other people's responses, they have said it may be due to the hormones being unbalanced and this can happen from bad diets and low nutrition. I dont really eat well, but ive been trying to drink green juice and eat more, but i dont gain weight and at some point i become ill and puke everything in my stomach out. Im normally ill a lot during winters. Another thing is that my period sometimes take like a few month start so their irregular but this is my first time to experience a long period. I just hope its my diet so i can work better on it. I also work on my health because i get ulcers that last a month also.
