Birth Control Pill

How Does it Work?

Pills (estrogen/progestin & progestin-only) prevent ovaries from releasing eggs. The cervical mucus also thickens to prevent the joining of sperm and egg. Both types can also prevent fertilized eggs from implanting in the uterus.

How Well Does it Work?

If taken correctly, the pill has a 95% success rate. However, birth control pills must be taken at the same time every day. The pill can also be ineffective if two or more pills are missed, if they are taken in the wrong order, or if the pack is started too late. The pill offers no protection against STDs.
