Contraceptive injection and Implant

What is it? An injection of the hormone progestogen.

How effective is it? Over 99%

Advantage: Lasts for 8-12 weeks - which means you don't have to think about contraception during that time.

Disadvantage: Side effects can include weight gain, headaches, mood swings, breast tenderness and irregular bleeding. The injection can't be removed from your body, so if you have side effects they'll last as long as the injection and for some time afterwards

How effective is it? Over 99%

Advantage: Works for 3 years (but can be taken out sooner).
