i am never delayed for my period, always on time or even a day earlier. today i am 4 days late and been having brown sticky discharge on and off for 2 days now. i have been feeling like i'm about to start my period for over 5 days already. i'd like to wait a few more days for AF. we only did the deed without protection one time 9 days ago (that was sunday, if i'm not mistaken) any ladies experienced this or similar, thanks
