Have acne now that I'm off the pill

The whole time I was on the pill (7 years) I had near flawless skin, I thought it was my natural setting. I have been off the pill since July (7 months) and my skin has gotten increasingly worse. At first it wasn't so bad but I think that was because my period didn't start up until December. Since December it has gotten worse and worse, especially on my cheeks. Does anyone have any advise for me?!
