nothing. the plan b pill is only good for 72 hours. wait the two weeks and test.
what can i do now after 4 days to lower the chances? and thanks
if it was the first pill of b/c and not plan b and you'd never taken b/c before yes it can still happen. it takes b/c 3-6 months to be effective. then it's still not 100%. which is why ob/gyn's recommend ALWAYS using condoms is you don't want a baby. whether you're on b/c or not.
pre ejaculate is secreted through penis during the entire sexual act...whether that is 1 second or one hour. so if there was any present yes you could end up pregnant.
and i took a contraceptiv pill less than 24 hours after
but for 20-30 sec can he do it?
if you were ovulating there is a 20-25% chance of you being pregnant. even if he didn't ejaculate there is pre ejaculate which DOES contain sperm. It takes one sperm to get you pregnant.
