I Missed A Birth Control Pill In The Second Week

I missed a birth control pill in the second week of the pack and have been on birth control for 2 years. I take my pill at 8pm usually but forgot and took it at 10am the next morning. I'm supposed to be getting my period and right now just have a thick white discharge. I have no other symptoms besides my boobs being a little sore. What are the chances I could be pregnant?
