Acne?

Okay so when I was a preteen-16 I had severe acne, I tried everything under the sun. The birth control pill has worked for the past two years If I take it consistently; which I have. But the past few days have been hell. I have backacne; I havent had since I was a kid; and my forehead is always oily. I have been using regular face wash in the shower and it usually works fine but now I'm a acne mess. My last period was really old as well. Mostly clots and no bleeding fully. It only lasted 4 days. So odd! Has anyone had this?
