How Does It Work?
The hormone progesterone in the birth control shot primarily works by preventing ovulation (the release of an egg during the monthly cycle). If a girl doesn't ovulate, she cannot get pregnant because there is no egg to be fertilized.
How Well Does It Work?
The birth control shot is a very effective method of birth control. Over the course of 1 year, fewer than 3 out of 100 typical couples who use the birth control shot every 3 months will have an accidental pregnancy. The chance of getting pregnant increases if you wait longer than 3 months to receive your next shot.
In general, how well each type of birth control method works depends on a lot of things. These include whether a person has any health conditions or is taking any medications that might interfere with its use. It also depends on whether the method chosen is convenient — and whether the person remembers to use it correctly all of the time
Possible Side Effects
Many young women who receive the birth control shot will notice a change in their periods. Other possible side effects include:
- irregular or no menstrual periods
- weight gain, headaches, and breast tenderness
