What Is The Cause Of Delay In Period?

hi, im 17 and very scared. i dont know what to do. my period ended about 2 weeks ago and a few days after it ended my boyfriend and i had unprotected sex. as it was the second time and still hurts and dosent go all the way in we decided to try without a condom. he pre cumed a few time, and im scared he precumed inside me. even though he hardly got in. also, i am now getting white discharge and when i wipe its brown. i have also been getting cramps but my period isnt due for 1 week and a half or so. could this mean im pregnant?
