2 Birth control failure is when for one reason or another your birth control will not work 100%. Maybe you missed a pill, took it late, or are on another medication that makes it not work. Birth control also includes other forms of contraception, like a condom ripping.

4 No. You should not take it more than once, it is emergency only as it's not good for your body and the more you take it, the less effective it is. Also, it's fairly expensive. Condoms are a better option. [ xokristabelle's advice column | Ask xokristabelle A Question ]

You need to take it within 72 hours of having sex, though, or it's rendered useless. It's really just a large dose of the hormones in regular birth control.
Plan B is, in essence, the "oh crap!" birth control. It's a lot easier, and less risky, to just get on a normal birth control regime. I recommend Nuva Ring. You don't have to think about it much. [ pseudophun's advice column | Ask pseudophun A Question ]

2. The definition of birth control failure depends on what type of birth control you're using. For condoms, it would mean that the condom broke, slipped off, etc. In general, it means that the birth control you're using has failed to prevent the chance of pregnancy. And any type of birth control can fail, although some are more likely to do so than others.
3. It's usually pretty easy to tell when you're using a condom. As mentioned, it'll break, slip off, etc. With other forms, like birth control pills, it's much harder to know that a failure has occurred.
4. Yes, it should work the same for you regardless of how often you have sex, what birth control you're using or not using, etc.
For the record, you're best off not relying on Plan B and sticking to using a reliable method of birth control every time you have sex. You may already know that, but just a reminder. =) [ WiseOldUnicorn's advice column | Ask WiseOldUnicorn A Question ]
