Okay first of all, I'm very passionate about women's health, & I research all forms of birth control very extensively. Second of all, most women starting birth control--and this is only for THE PILL, I'll add, but a ton of idiots somehow just accredited it to ALL FORMS OF BIRTH CONTROL WTF--started on it when they begin college. This is a common time for women to gain 10 to 15 pounds anyway, even ones who aren't on birth control. So a lot of doctors believe that the whole myth of gaining weight on birth control is solely attributed to the fact that women just happen to be taking it at a time that they happen to also maybe be gaining weight. Therefore, it is a myth!
