Birth Control? Am I Safe? - Missed Pill?

Ok so I started taking Yasmin birth control at the beginning of last month, so I have taken one complete entire pack but then I was one day late starting a new pack. I was supposed to start my new pack on Sunday, but I forgot, so I took a pill on Monday and have continued to take them every day since then. Now It's my boyfriends birthday on Saturday and I wanted to have with him without a condom, do you think this would be safe? Or am I at risk because I missed a pill?
