When your on birth control? u have no egg?

?? im kinda confused on that one.When your on birth control? u have no egg?
If you are taking a combination oral contraceptive pill one of the things the combination of hormones does is prevent ovulation. Since no egg is released from the ovary than a pregnancy can't result. In addition to suppressing ovulation, birth control pills also make cervical mucous thick so it is difficult for sperm to swim through. Plus, it makes conditions in the uterus unfavorable for a fertilized egg to implant. The combination of all these factors make oral contraceptives 99% effective when used as directed. If a woman is taking one of the ';mini'; pills it does not suppress ovulation but does make cervical mucous thick and the uterus unreceptive to implantation.When your on birth control? u have no egg?
Birth control pills keep your body from releasing eggs, therefore an egg cannot be fertilized.
