Hi, Almost Two Week Ago I Had Sex And The

Hi, almost two week ago I had sex and the condom broke. I missed my pill the night before and had it the next morning, and then had my pill for that day that night (however it was after we had sex). I took the morning after pill to be safe, but I'm on my 4th day of sugar pills and no period, just a light brown discharge today. Do I have anything to worry about?
