Switch birth control time

De`Ja
Hey ladies! I'm almost finished my pack of birth control (2 pills after today), but I need to switch the time to take it. Right now I take it at 3:20, but I want to switch to at least 6 or 7 because I'm going to college (Salisbury!) and I have a class at that time. So when an how do I switch the time without messing up my body???
