Can I change the day I start my birth control pack?

i started birth control 2 months ago (combination pill) and I started it on a Wednesday but now I end up taking the placebos and my period starts on a Wednesday too which is not convenient for my work. So if I start my placebo pills today (Wednesday), can I start the next pack this Sunday instead of Wednesday so that I will start my period on a Sunday instead? if that makes sense, is that okay to do or will it mess everything up?
