Sprintec 28/ Period

Patient: I’ve been on Sprintec 28 for almost 5 months. During the 4th month my period came a week early during the blue active pills instead of the white sugar pills like it usually does. Does this mean my period will come a week early during the 5th month or will it be delayed until the sugar pills? I’m nervous because I had unprotected sex while on my period during the 4th month.
