No. There may be a delay in regaining fertility after stopping monthly injections, but in time the woman will be able to become pregnant as before, although fertility decreases as women get older. The bleeding pattern a woman had before she used injectable contraceptives generally returns a few months after the last injection. Some women may have to wait a few months before their usual bleeding pattern returns.
You do need to have the injection once every month 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 4-12 weeks depending on the type, so if you miss an injection you will not be protected against pregnancy.
Some women think that the next injection should only be given when the next monthly bleeding begins. Bleeding episodes should not guide the injection schedule. However, a woman should receive the injection every 4 weeks or every 12 weeks depending on the type. The timing of injections should not be based on her monthly bleeding.
When you use injectable contraceptives you may have bleeding and spotting between periods. The menstrual bleeding may vary from slight staining between menstrual periods to breakthrough bleeding, which is a flow much like a regular period. It occurs most often during the first few months of usage, but may also occur after you have been using the injectable contraceptive for some time. Such bleeding may be temporary and usually does not indicate any serious problems. It is important to continue using the injections on schedule. If the irregular bleeding or spotting is heavy or lasts for more than a few days, you should consult your doctor or healthcare provider.
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 doctor or healthcare provider.
Periods and fertility may take up to a year to return after stopping injections, depending on the type of injectable, and this may vary from woman to woman.

It is difficult to tell whether such changes are due to monthly injections or to other reasons. There is no evidence that injectable contraceptives affect women’s sexual behavior.
Depending on the type of injection you choose, the birth control shot lasts for one to three months. To prevent pregnancy you need to receive a shot once each month, or once every three months, from a trained healthcare provider.
