A nurse gives Leena information about two methods of contraception. Leena wants to prevent pregnancy for the next two years. She often forgets routines, would like her fertility to return quickly when she stops using contraception and has previously experienced headaches when using hormones.
| Method | Information |
|---|---|
| Contraceptive injection | 94% effective during one year of typical use; releases a hormone for 13 weeks; may cause irregular bleeding; fertility may take time to return after stopping |
| Diaphragm | 83% effective during one year of typical use; must be positioned over the cervix for each episode of intercourse and used with spermicide; contains no hormones |
Discuss which method would best meet Leena's needs.
