need help

I started birth control 21 day pack on June 4 (Sunday) instead of being off 7 days I continued to take it and discontinued BC after I finished my second 21 day pack. It's aug 4 and there is no sign of a period. Could I be pregnant? I know people have taken a while to regulate but that's usually when your on them for a long time. This was my first time. Also I took them correctly everyday at 8:35 but on July one I took it at about 11;00pm. I need help
