Acceptance into college

Hi please help!
I accidentally marked my application to cal poly slo as early decision instead of regular decision. I am freaking out because early decision means binding and I had already submitted my application. How do I fix this error before I am admitted and legally binded to go there. Can I call the admissions advisors and notify them? Or should I just call the admissions advisors and cancel my application since cal poly was anyway a back up? Please let me know because I am panicking!!!

@PryankaS: Early decision acceptances have already been posted. Check your portal to see if the “Early Decision” portion of the message has been dropped. If so, then you have been deferred to RD.
