Method |
 |
A woman gets a shot of a combination of artificial hormones estrogen and progestin intramuscularly every month, which keeps her from getting pregnant. |
|
Success Rate |
|
Less than one woman in 100 will become pregnant in a year using this method. |
|
Benefits |
|
Once you get the shot, you don’t have to think about birth control for the rest of the month. |
|
Drawbacks |
|
Doesn't protect against STDs including HIV; also may cause slight weight gain as well as altered periods. |
|
How To Get It |
|
Requires a visit to a health care provider every month; the cost is comparable to birth control pills at about $25-$40 per month. |
