Did my problems magically disappear or what's going on?

Before I got on birth control pills when I was 13, my acne was the WORST. It was so bad that my whole face was red and with bumps it looked. All over. And my periods were extremely heavy, painful, irregular, unpredictable. So I got a gynecologist and she put me on a 28 day cycle pill after trying a few others and I was on that from August 2010 until last October of 2014. Then when I saw my gynecologist in October, I told her I want to get my period less often so we agreed to try Seasonique which is an extended cycle birth control pill. I stopped that pill at least a month ago. But my skin is still pretty clear and no period or anything.
