Switching methods guide
Editorially reviewed on October 29, 2026. [TODO: medical reviewer]
Quick answer
If you have been using your current method correctly, WHO says you can usually start the new one straight away with no gap and no backup. The main exception is coming off an IUD: overlap with pills for 7 days or use condoms. Confirm with your doctor.
| Switch | When to start | Backup |
|---|---|---|
| Pill to another pill | Start the new pack the day after the last hormone pill of the old one, with no break. | None if no pills were missed. |
| Pill to implant or injectable | Start any day while still taking pills consistently. | None if pills were taken correctly; follow your provider. |
| Injectable to pill or implant | Start up to the date your next injection would be due. | None if started on time. |
| IUD removal to pill | Start pills at least 7 days before removal, or use condoms for 7 days after. | 7 days if not overlapped. |
| Implant removal to pill | Start pills on the day of removal. | None if started that day. |
