my friend just told me that she had intercourse with her boyfriend on november 27 (thanksgiving) and took a plan b morning after pill the very next day! he had finished inside. she asked me if it was to early to see if the pill actually worked and wants to take an early pregnancy test. it's been 7 days. i told her to do as what the box says to wait and see if she gets her period. my question is... is it possible to find out right now if it did work? or is it to early into the process?
