Due to a monday holiday (stupid I know) I thought that Thursday was Wednesday and started my birth control pill pack a day late. I realized this on Friday when my first thought was that I did not take the pill on Thursday but soon realized that it was not that I missed a pill but that I had taken it late so I took two on Friday. Since I had had unprotected sex on Thursday morning with my fiance (thinking it was wednesday) I took plan B on Saturday around noon and have since continued my birth control pills as normal. What are the chances I am pregnant? How soon can I figure out if I am pregnant?
