I had unprotected sex with my boyfriend on march 13th and about 10 hours later I took plan be but then on march14th after I took it we had unprotected sex again,, will the plan be still work??

You need to check that with your doctor;as far as I understand one dose(two tablets) covers one unprotected intercourse.

Thus a second dose should have been taken after the second time you had unprotected sex.

You are aware of the 11% risk of still being pregnant after plan b I hope?

How about using a method of contraception,rather than a morning after pill?

Plan B should never be your Plan A.. . Hence the name. Good advice amicon

Like the others said, plan b is not intended to be used as regular birth control. If you're unsure if you are pregnant or not, you need to take a pregnancy test and you should see your doctor. No form of birth control is 100% effective, but you can at least decrease those chances of pregnancy and/or stds by learning about all of your birth control options and then using them correctly every time you have sex.
