Are you wondering if the contraceptive needle, also known as the Depo Provera shot, is the right method for you to prevent pregnancy? Before you get the injection, understand that there are a few women who should not get the shot. This includes women with bleeding disorders or who are taking anticoagulant medicines, undiagnosed abnormal bleeding, women with a history of some types of cancer, women who are already pregnant or wish to become pregnant within 12 months and women with any other serious medical problems.

That said here’s some insight into how the contraceptive needle works. You’ll be injected with a hormone whose effects will last for three months. It bears a great resemblance to progesterone, one of the two primary hormones that are produced by a woman’s ovaries during her normal cycles. When you have been given the Depo Provera shot, your body will sense the presence of the hormone and switches off your own hormone production.

In essence, your ovaries will not release an egg, keeping you from getting pregnant. It works in the same way as the Pill but if often considered more convenient by many women. The Depo Provera injection is a convenient way to protect yourself against unwanted pregnancies and is extremely effective. It is imperative that you receive your injections every three months when they are due or you put yourself at risk. The contraceptive needle is only effective when given on time every time. If you prefer not to take the pill, Depo Provera is a great alternative.
