Pregnant because of missed pills?

So this is my 2nd month on birth control (I am taking a generic of Junel FE). Almost 2 weeks ago I had unprotected sex without realizing that I had missed a pill that day (Sunday). I doubled up the next day, but the day after that (Tuesday) I missed another pill. Since then I have been taking it on schedule but I have been having a brown discharge since the day after I missed the first pill. Chances of pregnancy?
