I had unprotected sex on the last day of my period (03/03). Took a plan B pill (Next choice) the same day as an added precaution. Started to experience brown discharge on 03/04 and this is continuing until today (03/09). It was light discharge the first few days and today it got heavier. 

What does this mean? Is this normal??? At first i thought it was hormones cz of the pill. But isn't it supposed to stop after awhile? I am freaking out. PLEASE HELP! :-(
