I took plan b like 2 weeks ago and its been 14 days since then and i havent bled but im on birth control what does this mean? should i be concerned

About Plan B...: Plan B can alter the menstrual bleeding for the cycle in which Plan B was taken, and sometimes the next cycle too. One should be sure to check a home pregnancy test about 3 weeks after sex, because Plan B works most of the time, but not all the time. That said, couples having sex should always be ready for a rare, but cute, surprise baby... and getting married, settling down, raising a family,...

Plan B tx: Certainly a home pregnancy test is warranted.
