Is it bad my period is a week early?

I just finished my 3rd pack of alesse but my period didnt come during the sugar pills it came the last week of the hormone pills, this is the second month this has happened the first month i got my period on the sugar week. Ive tried 2 other types of pills so ive been taking it for about 9 months give or take a bit. Is this bad? what should i do? also should i stop taking the hormonal pills and jump right to the sugar ones to try to line up my period?
