Suggest Dosage Of Birth Control Pills-

I just received my package of birth control pills for the first time today, which has 28 pills. My doctor told me to start taking the pill 5-7 days after my next period comes, as I got my last one 1 or 2 weeks ago. I'm wondering if I can start the sugar pills first once i get my period, or do I start using the pills with the hormones 5-7 days after instead?
