Missed period?? need help

so i’m on the pill and i’ve taken it correctly. i haven’t missed a pill. i’ve been on it for almost a year now. me and my boyfriend have been having sex a lot like everyday and he pulls out every single time. my period was 4 days early last month but now it’s two days late this month but since january, my periods have been pretty consistent with a 28 day cycle. my period started july 6th last month and now it’s august 6th and two days late. i’m having some pink discharge today. could it be my period?
