Method |
When to start |
Combined oral contraceptives, progestin-only pills, combined patch, combined vaginal ring |
Can begin the day after she takes the ECPs. No need to wait for her next monthly bleeding.
- Oral contraceptives and vaginal ring:
- New users should begin a new pill pack or ring.
- A continuing user who needed ECPs due to error can resume use as before.
- Patch:
- All users should begin a new patch.
- All women need to use a backup method* for the first 7 days of using their method.
|
Progestin-only injectables |
- She can start progestin-only injectables on the same day as the ECPs, or if preferred, within 7 days after the start of her monthly bleeding. She will need a backup method for the first 7 days after the injection. She should return if she has signs or symptoms of pregnancy other than not having monthly bleeding (see common signs and symptoms of pregnancy).
|
Monthly injectables |
- She can start monthly injectables on the same day as the ECPs. There is no need to wait for her next monthly bleeding to have the injection. She will need a backup method for the first 7 days after the injection.
|
Implants |
- After her monthly bleeding has returned. Give her a backup method or oral contraceptives to use until then, starting the day after she finishes taking the ECPs.
|
Intrauterine device (copper-bearing or hormonal IUDs) |
- A copper-bearing IUD can be used for emergency contraception. This is a good option for a woman who wants an IUD as her long-term method (see Copper-Bearing IUD).
- If she decides to use an IUD after taking ECPs, the IUD can be inserted on the same day she takes the ECPs. No need for a backup method.
|
Male and female condoms, spermicides, diaphragms, cervical caps, withdrawal |
|
Fertility awareness methods |
- Standard Days Method: With the start of her next monthly bleeding.
- Symptoms-based methods: Once normal secretions have returned.
- Give her a backup method or oral contraceptives to use until she can begin the method of her choice.
|
* Backup methods include abstinence, male and female condoms, spermicides, and withdrawal. Tell her that spermicides and withdrawal are the least effective contraceptive methods. If possible, give her condoms.
