you have to actively be taking birth control at the time of the unprotected sex or condom mishap or whatever happened that may make you think she could be pregnant.


Taking Birth control AFTER will have no effect. However, there is plan b which is effective up to 72 hours after sex. If it has been longer than a week I would have her take a pregnancy test to be sure otherwise go into planned parenthood and they can test her. Its possible she is just getting ready to start her period and its just cramps.


good luck!How long does it take when you get a girl pregnant for birth control not to work?
You have to take birth control BEFORE you have sex, not after, and she has to take it at the same time every single day. Are you talking about the Plan B pill? Plan B is only effective 72 to hours max after you have sex, so if it's been longer than 3 days you just have to wait an see. If you don't want a kid, you should either:


1 - not have sex


2 - EDUCATE YOURSELF about protection before you get yourself into these situations.
Birth control is supposed to be taken before the act, not after.


It will not make her unprego.





Its even to late for the morning after pill that you can just but at the drug store.





You will just have to sweat this one out, but remember how you feel now so it don't happen again.
you shouldn't phuk if you dont want a kid.





the pill that she takes (or should take) kills the egg before your sperm fertalizes it... what good would it be if she takes it a week after you insemidated her? For it to work correctly wait 2-3 weeks, take the pill (both of you) you want to cover all of your bases.. and hope for teh best. Good luck!





And I'm serious... you shouldnt phuk without at least a few condoms even if she ';wants it REAL bad';
