Late for Your Contraceptive Injection? Here's What to Do
Quick Answer
If your contraceptive injection (Depo-Provera) is more than 2 weeks late and you've had unprotected sex, emergency contraception is recommended. Get your injection as soon as possible and use backup contraception for 7 days.
When Is Your Injection Considered Late?
Depo-Provera is typically given every 12-13 weeks (about 3 months):
- On time: Within 13 weeks of your last injection
- Acceptable window: Up to 2 weeks late (15 weeks total)
- Late: More than 2 weeks overdue
Protection may be reduced once you're more than 2 weeks late.
Do You Need Emergency Contraception?
Assess your situation:
| Situation | EC Needed? | Action |
|---|---|---|
| Less than 2 weeks late, no sex | Get injection ASAP | |
| Less than 2 weeks late, had sex | Usually no | Get injection ASAP, protection likely intact |
| More than 2 weeks late, no sex | Get injection ASAP + use backup for 7 days | |
| More than 2 weeks late, had sex | Take EC + get injection + backup for 7 days |
Which EC to Choose
Either Postinor or Mifestad can be used:
- Both are effective regardless of your usual contraceptive method
- Choose based on timing (Mifestad if closer to 72+ hours)
- Neither will interfere with your injection schedule
Getting Back on Track
Here's your action plan:
Take EC if you've had unprotected sex while overdue
Schedule your injection appointment immediately
Get the injection as soon as possible (don't wait for your period)
Use backup contraception (condoms) for 7 days after the injection
Consider setting reminders for future appointments
Having Trouble Keeping Up with Injections?
If you frequently miss injection appointments, consider:
- IUD: Lasts 3-12 years, nothing to remember
- Implant: Lasts 3 years, inserted in your arm
- Monthly reminders: Set calendar alerts for your appointment
- Different method: Pills, patches, or rings might fit your routine better
