"i&#039;ve been on the shot for about 2 and a half years. the first few times i got the shot i had some inconsistent spotting. i could never tell when it would occur. after a while my body adjusted and i haven&#039;t bled since. before i got in the shot i weighed about 98 pounds and now i&#039;m at 110. the shot does not make you gain weight. the shot increases your appetite and it&#039;s what you eat and how much you eat that makes you gain weight. however no one informed me about the fact that it weakens your bones until about 1 month ago."
