Taking Junel Fe 1/20

I have been taking Junel Fe 1/20 for one year now.  I usually get my period between the first brown pill and the second.  I just started my period today and I still have 8 pills left until I start week 4.  Do I continue taking the yellow pills and then take the brown pills when I get to week 4, or do I need to start taking the brown pills now and then start a new packet?

Thank you,

Sharon
