I am asking this question for my girlfriend (and me).

Basically she wants to change her birth control start date from Thursday to Sunday. Her inactive pills have ended today and the doctor told her to wait until Sunday to start her new pack. The thing is my girlfriend forgot to mention that we've had unprotected sex last Saturday. Is it safe for her to skip Thursday's, Friday's, and Saturday's pill? She is supposed to have her period tomorrow but I don't think it's a good idea to base this whole plan on her getting it tomorrow. Also I should mention that she has taken all active pills on time.

Here's a time line:

Saturday:Unprotected sex. Inactive pill.
Sunday: Inactive pill.
Monday:Inactive pill.
Tuesday: Inactive pill.
Wednesday: Last inactive pill. Doctor says to wait till Sunday.
Thursday: Hope for a period. Wait to start new pack.
Friday: Skip, wait to start new pack.
Saturday: Skip, wait to start new pack.
Sunday: Start new pack.
