THE PATCH

So I went to my gynecologist yesterday to get put on birth control after I passed out and hit my head from the severe cramps I got from my last period. We decided that the patch might be the best option as I can be super forgetful. I'm 19 and not sexually active. I am super concerned about the side effects however, especially the whole "weight gain" thing as I am already self conscious as it is. What are your experiences with the patch? Did it make you gain weight? Tell me everything!
