I'm 15 and due to changing my eating habits, I went from 142 to 113. I'm 5'5" and a half and am a tennis player. I've missed my period 6 times in a row now, does this mean that when I grow up I can't have kids?
if you too skinny or have too much weight on will mess up your period and could prevent it from coming.... also being that you play sports is also a factor
you have lost too much weight or lost it too fast. if you are underweight you will not get your period. it can randomly show up again once your body settle down but you should see a doctor anyway because if it doesn't it can affect your ability to have children one day
