Stress or Pregnant?

Lexiiii

I have chronic anxiety from my past and think things over terribly. I would love to have someone to talk to about my situation for that i’m still young and need comfort!! I had unprotected sex on November 21 and he pulled out 30 seconds before he finished i also was two days before ovulation/fertile window. However my period is 10 days from today and i have clear watery discharge and tiny sticky brown pieces that i read that could be hormonal off balance from extreme stress. What could it be?? Someone help me PLEASE . I am very worried
