She's worried sick, but I'm trying to keep my head, but anyway, here's the deal:

-Her and I went on a trip to California last week, and (not wanting to have her period during the week) she pushed back her period by a week using the birth control that she has been on for the past 3 years.

-She is on birth control, and has been missing very few days of late.

-We have had sex 2 or 3 times since her last period.

-Every time we have had sex we have used a condom, which I am sure that I have used correctly and it has not broken.

-Her period is 4 days late. She had some cramps a few days ago but is claiming that they are gone now.

The thing that I'm worried about is that pushing her period back may have messed with the protectiveness of the pill. Anyone have any advice or opinions on this? Anything would be really, really helpful and appreciated.
