The morning-after pill is a type of emergency contraception that is used to prevent pregnancy for women who have had unprotected sex or whose birth control method has failed. It is not intended to be used as a primary method of birth control, but rather as a backup option. The morning-after pill works primarily by delaying or preventing ovulation, which is the phase when the ovaries release an egg that can then be fertilized by sperm and begin the fetal development process. It can also prevent fertilization or keep a fertilized egg from implanting in the uterus. It is important to note that the morning-after pill does not end a pregnancy that has already implanted.
The morning-after pill is available in two types: levonorgestrel (Plan B One-Step) and ulipristal acetate (ella) . Levonorgestrel is available over-the-counter without a prescription, while ulipristal acetate requires a prescription. Both types of morning-after pills are most effective when taken as soon as possible after unprotected sex, but can be taken up to 5 days after.
Side effects of the morning-after pill may include nausea or vomiting, dizziness, fatigue, headache, breast tenderness, and bleeding between periods or heavier periods. It is important to talk to a healthcare provider about any concerns or questions regarding the morning-after pill.
