User avatar Hello,
There is a chance, since no birth control is 100% effective except abstinence but it is not likely based on the information provided here. I suspect your period has been affected by the high level of hormone in plan B and possibly stress. If your period does not start in a week or so, you could take a home pregnancy test for peace of mind. The hormones will not affect the results of the test.

Best wishes.
