Birth control linked to depression?

Michelle
I recently read this article from the Washington Post that talks about studies suggesting that women on birth control pills have a higher risk of suffering from depression.

After being on the pill for 10+ years, I recently got off the pill to see if I can treat my mild PCOS naturally through healthy eating, loose weight more easily, increase my libido, and see if my depression is simply situational. What are your experiences with depression and birth control? Do you agree with the artcle? I know we all experience the blues/stress, so how do you know if your depression is serious? Looking forward to hearing your thoughts and experiences with bc!
