Started the pill

The day I started my pill (sprintec) was the day I started my period so my doctor gave me the pack but took out 4 of the 7 sugar/placebo pills. I am down to my last sugar pill today and I don't know whether or not to start a new pack or wait 4 days because of the missing sugar pills. PLEASE HELP! Oh and I have not started my period yet, it should start in 5 days if that matters.
