Birth Control Causing Acne...

Brittany • Brittany • 24 • Tom is my saving grace. I love you <3 6.30.14 <3
What is a good inexpensive way to get rid of the acne my birth control causes???
-
I get black heads on my cheeks and near my nose. Whiteheads on my chin. And all kinds of red pimples raised and flat throughout my whole face. My acne IS NOT EMBARRASSINGLY BAD but I want it gone.
-
Things like Proactiv I consider expensive and I'm allergic to it. A lot of products dry my skin out. 
-
Right now I have Aveeno acne solutions. It's not a soap. Works a little. Plus neutrogena pink grapefruit acne wash.

Nothing seems to work!!! I hate my complexion too!
