Question: How Do Birth Control Pills Prevent Pregnancy?
Answer: Birth control pills, also known as oral contraceptives (OC's) have the main goal each month of preventing your reproductive system from releasing an egg. Generally speaking, birth control pills prevent pregnancy by suppressing ovulation. Another way that birth control pills prevent pregnancy is that they encourage the cervical mucous to be thick and tacky. Finally, birth control pills help to make the lining of the uterus less receptive to implantation.
