If you would like a non-invasive and discreet contraceptive method, the contraceptive injection may be suitable for you. The contraceptive injection is an injection of hormone that provides long acting protection from unplanned pregnancy. It works by slowly releasing the hormone progestogen into the body to prevent ovulation. Irregular bleeding is a possible side effect of the contraceptive injection, however, with time, no periods is common and may be an advantage for some. You should not use this contraceptive method if you do not want your periods to change. The contraceptive injection is a very effective family planning method (over 99% effective with perfect use) and is more reliable than the contraceptive pill, as you only need to remember to have the injection every 12 weeks, instead of taking a daily pill. It is important to have a repeat injection on time, every 12 weeks, otherwise it becomes ineffective; hence its effectiveness is only 94% with typical use. It doesn’t offer any protection against sexually transmitted infections or HIV/AIDS.
Long term use of the contraceptive injection may reduce the mineral content of bone in some women, which is likely to be reversible when the injections are stopped. Because of this, if you are under 18 or over 45, the injection may not be the first choice of contraception for you. It can also delay your return to normal rates of fertility.

Some women may experience longer periods or continual light bleeding for some weeks and in rare cases heavy bleeding may occur. A small amount of weight gain may occur with the contraceptive injection, but a large increase in weight is uncommon. Other side effects are uncommon but headaches, acne, moodiness, a loss of libido, bloating and fluid retention can occur for some women.
