The contraceptive injection is a shot that contains hormones, either a progestin alone, or a combination of progestin and an estrogen, that stops your body from releasing eggs and thickens the cervical mucus. This method requires you to receive a shot from a healthcare provider either once a month or every three months. However once injected, it is irreversible; side effects from the injection cannot be stopped once they manifest.
USAGE As with most contraceptives, contraceptive injections are not the ideal choice for everyone so getting advice from a professional is always recommended. Depending on the type of shot you get, you will need to go back every month or every three months for another shot and you’ll be highly protected in between.
