Re: getting ur period
birth control pills probably won't make you gain weight.
also, the horomones that cause your period (estrogen) are stored in fat. that sounds bad, but it isn't. women natrually have a layer of fat under their skin so they can store this horomone, and have kids. if there isn't enough fat on a woman's body, then the horomones have no where to be stored, so they disappear.
you should see a doctor to see what he/she says about you going on birth control
Peace out loves,
