Acne and irregular periods.

I'm 25 years old and recently have developed HORRIBLE cystic acne!! I've always had irregular periods but within the past few years they became regulated and monthly. Recently, my periods became irregular again. I have no concern of pregnancy, but I am curious to know if these two issues are related. At my yearly check up in March everything was normal.

Has anyone gone through the same thing? Or possible have any suggestions or feedback?
