Does the contraceptive injection have any long term side effects?
Many women are very happy using the contraceptive injection every 3 months, and often they have no periods at all after a while. Caution is advised for women on it for over 5 years as it can result in thinning of the bones (osteoporosis) especially if there is a family history or if you smoke. The injection is not recommended if you are thinking of pregnancy in the near future, because the return of your fertility can be delayed after it is stopped.
