I'm taking aubra the combination pill, I've been on BC since November 2013. I originally started with lutera and they changed it on me this November but said it was the same pill but a different name. Okay so I started a new pack on Thursday. My period ended on Friday. I usually get it from sunday-Friday. I took the pill a little early on Friday around 6 PM, and my usual time is 7 PM. Saturday night I took it around 11 PM because I worked late and late Saturday night around 1 am I had unprotected sex but he pulled out. Is there a chance I could be pregnant?? Does it matter that I took it 24 hours later then the other one?
