Plan b on feb16 48 hrs after unprotected sex got period in time but light with some clots now having brown stretchy discharge wk before period. prego?

Possibly: If it's a week before your period, you could consider a home pregnancy test. If it's negative, consider repeating it in 5-7 days. 48 hours is awhile to take Plan B after unprotected intercourse. First piece of advice, have a more reliable form birth control. Second advice, have Plan B at home already so that you increase your chances of taking it on time, should condom break, etc.
