I had my period maybe December 27,2014 and I was going off but light bleeding January 2,2015 I had sex that day and I took the plan b pill maybe 8 hours after sex. Since then I have been spotting for almost 3 weeks now it's now January 31,2015 and still I'm spotting here and there with a discharge( smells funny)I am a bit worried this is not the first time I had taken plan b and I never experienced these symptoms is it possible that I may be pregnant? ??....
