Question about Birth Control Pill.?

I take Yasmin. I was in my 2nd week of pills. Thursday I took my normal pill in the morning. Then Thursday night, I took Friday mornings pill (I was tired and just wasn't thinking). So then Friday I didn't take a pill, since I took it the previous night. And I resumed back Saturday morning. Do you think I have a chance of becoming pregnant? I had Friday and Saturday. Do you think I was still protected with the birth control?
