I am on the birth control pill tri low. I have been on it since the beginning of the year. Since I am on the pill I do not use condoms and my fiance does ejaculate in me. I just began a new pack about a week ago. I took up to day 7 but forgot day 8,9, and 10. My finace and I had sex on day 9 and he did ejaculate in me. What are my chances of being pregnant?
