I’m not sure I understand your timeline here.
If you received your DepoProvera injection within 2 weeks after giving birth, it was effective within 24 hours. The injection is effective for up to 12 to 13 weeks. If you did not return for your next injection, then you are not protected. If your bleeding occurred after your “missed” shot, then yes, you could get pregnant.
If you’re not sure, do a home pregnancy test. If you wish to continue the Depo as your method of birth control, call your doctor or clinic to be restarted on it. In the meantime, abstain from sex or used condoms to prevent pregnancy.
