Your questions
We've collected together the most frequently asked questions about contraception, to ensure that you can find the right contraception for you.
The injections must be given by a healthcare professional. Depending on where you live, you can have the injection done at your local doctors practice or family planning clinic.
You do need to have the injection once every two months or every three months, depending on the type of injection you have. The amount of hormone which is injected to prevent unintended pregnancy will only last around 8-12 weeks, so if you miss an injection you will not be protected against pregnancy.
If you are sexually active and do not currently wish to have children, you can continue having the injections to protect against pregnancy, providing you find the method suits you and you have regular check-ups with your healthcare professional.
Some women do experience weight gain. If this happens to you, speak with your healthcare professional, it may be that an alternative form of hormonal contraception is better suited to you.
