I own hear empire say-so...
Answers: you will gain a bit weight..but its not like when you grasp it your going to be 150lbs..i dont think you will have to gain any if your fluently small and still eat normally..it will come.
everybody starts their term at different ages- my mom started hers at age 8- glad it wasnt me-but some girls dont start til they are 18 or 19- its different for everybody- dont worry, it will happen when its prepared. there is nothing you can do to hurry it up or to slow it down - you only have to wait. You can NOT attain your period because of low body fat, this happen to serious athletes sometimes, but so long as you are healthy, and not rigorously training and purposefully keeping your body fat down, you should win your period when you are supposed to..
I heard a girl requirements to be at least 80 lbs.
either that or you could be a behind bloomer which is fine. I wouldn't stress on it you are so young, it may not happen till you are 16, that's okay, relax and be a kid, enjoy fun you're not missing anything. no you don't have to gain weight
you will find it when your body's ready..
usually if they're really thin and can't gain it - they have a problem..
if you're healthy after don't worry about it
it could embezzle ages
you will get it eventually .
Don't concentrate to others word. If your body is prepared for it your period will start automatically. Period depends on hormones which are released by your body, not depends on counterweight or how you look are(fat or thin). dont worry u prob might not get it til ur 16. ive hear of people getting it wen they r 18 and theres nothing wrong beside that it depends on how fast ur body developes not so much ur weight and point (although thous r sometimes signs) .
it doesnt usually matter how much u weigh it depends on when your body is ready.

you dont own to gain weight.
it will come when it should.
