"i&#039;m 18 and i just started birth control for the first time to help with acne and my doctor prescribed levora. i have only been taking it for 4 days and i have an extreme decrease in appetite. the first day i felt fine, just not hungry, and the second third and fourth days i have been very nauseous every morning and i think i have lost weight. i am hoping this will go away and my skin will eventually be clear!"
