I had unprotected sex on the 5th of my period and I took Plan B within 12 Hrs, it is now my 13th day of my cycle and I'm spotting. I have never spotted before so it is not normal for me, I also noticed that my vagina smelled different than normal on the 10th day of my cycle. Not fishy or bad, just different smell. Is this a sign im pregnant or is this normal after taking Plan B?
