I don't know your age but your hormones do change as you get older. The pill I was taking when I was 28 is not the same one I am taking at 34. It could just be that simple, but of course you need a doc to make sure! On a side note, when I turned 30 my started to break out like I was a 16 year old boy. My hormones fluctuated and changing my birth control REALLY helped.
