I used a condom and after i finished i stayed inside. once i pulled out the condom was still inside of her but not the base should i still use plan b?

Better to B safe...: PopoN133, Rest assured that if the condom did not break then it should be as effective as usual. I often recommend plan b if someone is concerned and aren't in the position to be able to support a child. Keep in mind that plan b should be taken within 72 hours of the event! She should clear this with her doctor. There may be a reason NOT to take it! i.e. interaction w another medication.

YES: If there is a chance that the condom emptied while inside the vagina there is a possibility of pregnancy. I strongly suggest a home pregnancy test.
