Concerned

Last period was from January 2nd to the 6th. I had sex ones this month during my most fertile day (January 15) he came first with a candom and then we had sex without it and he came but pulled out. Precum might have gotten in me. I was expecting my period on January 30th but woke up with a very light brown discharge (never happened before) I tested on the 30th & it was negative. On February 2nd I also tested and it was negative. It is now February 4th & still no period. (5 days late). Should I still expect pregnancy or not?
