Silly question

I know this is probably a dumb question but I just need help getting this is my head lol. So I recently changed my pill from 8am to 7pm( combo pill) and I’ve taken it every day at 7 for the past 3 weeks my period is supposed to start tomorrow and after my pill free week I’m still protected, correct? For some reason I think it won’t be effective taking it later in the day. Like when I took it in the morning I knew I was protected all day and night until the next morning ( if that makes sense) but now after the pill free week I have to wait until 7pm to take it
