My g/f started her ortho and is on the inactive pills of the first pac (generic tri-sprintec) switching to Ortho. We are going out of town this weekend, she will have two pills left. Is it ok to go ahead and have sex?
If she took all 21 active pills perfectly. Then she is protected from pregnancy during the inactive week.
If she is changing brands? It shouldn't matter as long as she starts the next pack up the day after her last inactive pill in the tri-sprintec. (1 pill every day! She should take the inactive ones so she doesn't forget to start the next pack on time)
