If you are on the pill, and starting your placebo week, but you start your period early, do you start a new pack?

Sorry if this is a dumb question... I really hate my period cause I’m very irregular (Been this way for years. I’m 27 now) but I’ve literally never tried taking the pill as birth control (have had the implant, and iud before) but now my doc has me taking the pill to regulate my period... so I’m a little embarrassed to admit I don’t quite know how to take them. Yes, I take them every morning before work, I get that. But since I’m so irregular, I’m not syncing up to the packs. I’m supposed to start a new pack next week but my period came early (today) while I’m still on the placebo week. Do I just toss this pack and start the new one?
