Messed up birthcontrol and the condom broke so i went on planb 10 days ago..3 days ago the condom broke again, i hav spotting is it from planb or preg?

Can do a preg. test: Plan B can alter the menstrual bleeding for the cycle in which Plan B was taken, and sometimes the next cycle too, so there may be some irregular spotting. The birth control pills should be continued on their regular schedule. 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.
