Periods with Plan B: Periods can get very off schedule with the use of Plan B. Even with the break of a condom, if you took plan B within 48 hours of the incident, then it is very unlikely are pregnant. If it is time for your period, you can certainly do a pregnancy test, and if negative , repeat in 3-4 days. Don't be too concerned though, about unusual timing of periods after using Plan B.
