No period yet

Sarah
So on May 26 I started my period and my Dr. told me to start my pill (Junel Fe) so I had my period for the first 4 days of the active pill. When I got to the 4th week (the pill with no hormones) I did not get my period. I am now a week into the next pack of active pills and still have not gotten my period. Should I be concerned? My boyfriend and I do not use condoms, he always pulls out. I'm scared though my period is usually no more than 4 days late.
