10 Best Methods of Birth Control

8. The Diaphragm

A diaphragm is a rubber-like barrier that goes in your vagina and blocks sperm from entering your uterus. To ensure a proper fit, diaphragms come in different sizes (your doctor can fit you for one). It’s recommended to use spermicide in combination with this method to help immobilize or kill sperm. You don’t want any of them trying to sneak their way in! There are no hormones involved—just pop the diaphragm in before you have sex, and leave it in for six hours after.
