Next Depo-Provera Injection Window
Schedule your next Depo-Provera injection at 13 weeks (91 days) from your last injection, with a grace period extending to 14 weeks (98 days) without requiring backup contraception. 1
Standard Scheduling Window
The repeat injection should be administered every 13 weeks (91 days) as the standard interval recommended by the American Academy of Pediatrics and FDA labeling. 1, 2
You have up to 14 weeks (98 days) from your last injection to receive the next dose while maintaining full contraceptive protection without needing backup contraception. 1
Many providers schedule appointments at 11-12 weeks to provide a buffer for missed appointments, ensuring you stay within the protective window. 1
If You Miss the 14-Week Window
If more than 14 weeks have passed since your last injection, you can still receive Depo-Provera if reasonably certain you are not pregnant, but you must use backup contraception (condoms or abstinence) for 7 consecutive days after the injection. 1
Consider emergency contraception if unprotected intercourse occurred within 5 days before receiving a late injection. 1
Early Injections
There are no time limits on early injections—you can receive your next dose earlier than 13 weeks if necessary (e.g., travel plans, scheduling conflicts). 1
Early administration does not compromise effectiveness or safety. 1
Critical Timing Points
Within 14 weeks (98 days): Full contraceptive protection continues, no backup needed 1
After 14 weeks (>98 days): Can still receive injection but requires 7 days of backup contraception 1
Ovulation suppression lasts at least 14 weeks after a 150 mg intramuscular dose, which is why the 14-week window exists. 3
Common Pitfalls to Avoid
Do not delay receiving a late injection out of concern—it can be given at any time if reasonably certain you are not pregnant, though backup contraception will be needed if beyond 14 weeks. 1
Do not assume you need to wait for your menstrual period to receive a late injection—immediate administration with backup contraception is the correct approach. 1
Always use condoms regardless of injection timing for STI protection, as Depo-Provera provides no protection against sexually transmitted infections. 1
