Period late, im on birth control hvent missed a pill this month, had sex day of ovulation, never happend before, am i pregnant? period always on time

Many possibilities: The combination birth control pills prevent pregnancy by preventing ovulation (almost all the time), so you weren't likely having sex on the day of ovulation. Taking them consistently is important for them to be effective. If you've been on the pill for a long time, bleeding can slow down or stop. But to be sure--take a home pregnancy test, keep taking the pill, and check with your doctor.
