How to Switch Birth Control Methods

The Short Answer

You can switch birth control methods at almost any point, and most switches are straightforward. The main thing to get right is timing: you want to avoid a gap in protection. Generally, that means starting the new method before stopping the old one, or using backup contraception during the overlap.

General Rules for Switching

1. Start the new method before stopping the old one whenever possible.
2. If there is a gap, use backup contraception (condoms) for at least 7 days after starting the new method.
3. Switching from any method to an IUD or implant: These can usually be placed at any point in your cycle. Your provider will advise on whether backup is needed.
4. Switching to or from the shot: Timing matters more because of the shot's 3-month cycle and delayed fertility return.

Switching from the Pill to an IUD

1. Continue taking your pills until the day of your IUD insertion appointment.
2. The IUD can be inserted at any point in your cycle.
3. If the IUD is inserted within 7 days of starting your period, no backup is needed.
4. If inserted at another time, use backup for 7 days (continuing pills until insertion day usually covers this).
5. Stop taking pills after the IUD is placed.

Switching from the Pill to the Implant

1. The implant can be inserted while you are still on the pill.
2. If inserted during the first 5 days of your period, it works immediately.
3. If inserted at another time, use backup for 7 days.
4. Stop taking pills after the implant is placed.

Switching from the Pill to the Patch or Ring

1. Start the patch or ring on the day you would have started a new pill pack.
2. No backup needed if you switch on the correct day.
3. If you start mid-pack, use backup for 7 days.

Switching from an IUD to the Pill

1. Start the pill 7 days before having the IUD removed.
2. This ensures continuous protection with no gap.
3. If you cannot start early, begin the pill on the day of removal and use backup for 7 days.

Switching from an IUD to the Implant

1. The implant can be placed at the same appointment the IUD is removed.
2. If placed within the first 7 days of your period, it works immediately.
3. Otherwise, use backup for 7 days.

Switching from the Shot to Any Other Method

Because the shot provides protection for 12-13 weeks, you can start a new method while the shot is still active:

1. Start the new method on or before the date your next shot would be due.
2. If the new method is an IUD or implant, have it placed before the shot wears off.
3. If switching to pills, patch, or ring, start them at least 7 days before the shot's protection ends.

Important: Fertility return after the shot takes longer than other methods (6-12 months). If you are stopping the shot to try to conceive, there is no medical intervention to speed up the return of fertility. Be patient and track your cycle.

Switching from Any Hormonal Method to the Copper IUD

1. The copper IUD works immediately upon insertion.
2. You can stop your hormonal method the same day the copper IUD is placed.
3. No backup needed.

Switching from Any Method to Condoms Only

1. Use condoms from the first day you stop your previous method.
2. No transition period needed.
3. Be aware that typical-use effectiveness of condoms (82%) is lower than most hormonal or long-acting methods.

What to Expect During the Transition

• Breakthrough bleeding or spotting is common for 1-2 cycles during a switch.
• Your cycle may take 1-3 months to settle into a new pattern.
• Hormonal side effects from the new method may appear during the first 2-3 months.
• Mood and energy changes are possible as your body adjusts.

Frequently Asked Questions

Do I need to take a break between methods?

No. In most cases, you should not take a break because that creates a gap in protection. Overlap or start the new method on schedule.

Will switching methods mess up my hormones?

Switching may cause temporary side effects (spotting, mood changes) as your body adjusts, but it does not cause lasting hormonal disruption. Your body will adapt to the new method within 2-3 months.

Can I switch methods on my own, or do I need a provider?

Switching between pills, patch, and ring can often be done on your own with guidance. Switching to or from an IUD or implant requires a provider visit for insertion/removal.

Is it safe to switch methods frequently?

Switching is safe. However, frequent switching means more adjustment periods. If you are unhappy with your current method, talk to your provider about what specifically bothers you - sometimes a dose adjustment or different formulation can help without switching the entire method type.
