Hello, I am currently on the combination birth control pill. I am ending on my second week of the cycle. Yesterday was Friday and I realized when I took my pill, it was on the "Thursday" slot. I must have forgotten to take my pill one day, but was still taking one pill the next days. However, I did not double up because I was not aware that I had missed a day since I was probably not paying attention to the printed days on the container. So, I've technically only missed one and have been behind 1 day for a few days. I'm not even sure what day it is I missed. My boyfriend and I had unprotected sex on week 1 and he may have ejaculated some in me, but I don't believe I missed the pill during that time. What are my chances of becoming pregnant?
