I’m on birth control (have been for 6m now) but I started my period a week early?

What does it mean when my period comes a week early while I’m on the pill. I’m literally taking the highest dose week right now and somehow my period is just coming anyways. Should I just stop this pack and start a new one on Sunday? Should I keep taking them even though it might give me a 2w long period?

Wtf?
