Well i took the plan b and after i had sex about 2 times and he put his semen in me but then after i took another plan b is the plan be going to work?

Plan B should work: Plan B works most of the time, but not all of the time. One should do a home urine pregnancy test 3 weeks after taking Plan B. Also, use a reliable form of birth control all the time, so that emergency contraception such as Plan B will rarely be needed (hopefully never) in the future. Most woman should need Plan B only once or twice in an entire lifetime.
