Often does not occur: Most birth control pills, when taken on schedule, do prevent ovulation. Even if ovulation occurs conception may still be prevented as the hormones in the pill thicken the cervical mucus, preventing entry of sperm into the uterus. They can also change the lining and motility of the fallopian tubes such that the egg is not transported to the uterus.
