no, please dont beleive everything you read/hear. because this ones a total lie. women gain weight regardless if they have there period or not, and regardless of wether theyve started it or not. having a period doesnt affect weight, you are still able to gain weight and/or loose it. surely youve seen thousands of overweight women (and men) by now, and those older women would have obviously had got there period long ago
No, you can gain weight whether you have a period or not. However most girls grow significantly slower after their periods.
Of course that is not true. You see plenty of grown men and women gaining weight, losing weight, then gaining it back!
Huh? You can gain weight at any age no matter if you've started your period or not.
