I normally start my pill pack on a Monday, but I was late by 24hrs and took it on Tuesday. I believed this would be no big deal because I would use condoms, but low and behold the condom broke! After that, I took an extra pill (I had already taken my first one a few hours earlier). I wasn't originally going to double up, because I usually get sick from doing so and like I said, I was just planning on using condoms for a week. Anyway, do I need to go buy Plan B? Or is doubling up enough in this case?

Thanks in advance!
