My girlfriend accidentally started taking her next month's pills without taking the fake pills for the 7 days. Her period should have happened three days ago and she is all nervous (even though we don't have unprotected sex on my end) and i'm wanting to assure her that since she took her pills when she shouldn't have, that now her period time will be messed up. Is this correct and what should she do in regards to starting to take her pills again?

Thanks!
