Birth Control: Diaphragm and Cervical Cap
The diaphragm and the cervical cap are cup-shaped devices that are inserted into the vagina. They protect against pregnancy by covering the cervix. They keep sperm from entering the uterus to meet the egg.
Talk to your healthcare provider about the effectiveness of this birth control method.
