Type: Short Acting
The contraceptive injection is a shot that contains hormones that stops ovulation (the process where an egg is created) so no ovulation means no egg for sperm to fertilize. You need one shot either once every month or once every three months from a clinic or hospital. However once injected, it is not reversible, i.e. in case of side effects it cannot be stopped. The way it works is similar to the pill, except you don’t have to remember to take it every day or week, but it probably isn’t the best choice for those scared of needles.
