Birth control?... Not sure which one to go on.

Brittany • Brittany • 24 • Tom is my saving grace. I love you <3 6.30.14 <3
I have a gynecologist appointment today with a new doctor and I'd like to go on birth control.
~
Which birth control are you on?
~
I'd like to go on one that is low hormones (I'm bipolar so I don't need a BC that will whack me out more)
~
Won't make me gain weight (I'm around 130lbs)
~
Clear my acne (I have bad acne on my face, chest, and back)
~
Not get me pregnant
~
Any suggestions?
