I've been on oral contraceptives for about 7 months (since February) and I have yet to miss a pill so I take them on time daily, strictly. The latest I have taken a pill would be within a three hour period. I know while being on the pill, it prevents my body from ovulating but out of curiosity I use an app to track my periods and my "fertile" window. My boyfriend ejaculated in my during 3 days out of the 5 or 6 days of my window/ovulation period. While I am on the pill, what are my chances of becoming pregnant?
