What is going on with me?

Well ive had unprotected sex and used the "pull out" I know it doesnt work but still. I was suppose to start June 8, but it never came took a hpt Saturday. Wel i still havent started..Sorry to be gross but I also have a discharge but this time its light brown. I heard that it is a early sign of pregnancy. my stomach been cramping, but thats it. Should i take a nother pregnancy test? Its been two weeks not starting...... Ive been off birthcontrol for 2 months
