If I had sex immediately after my second Depo injection, was I protected? #811/12

Hello this is my first time EVER doing this, but I need a real answer and FAST PLEASE... Well, I got my Depo shot 5 days ago for the second time. I got it exactly 12 weeks after the first injection and I just had unprotected sex (he ejaculated in me). I would like to know if I'm protected or should I start stressing out?  Please let me know soon as possible so I can run for a Plan B pill.  I am only 16 year old.


Actually a woman is protected for 17 weeks after her last Depo injection.  You were definitely protected!

 

The following is an earlier question and answer concerning this same subject:

 

Trigger Question:     What is the latest information on the length of effectiveness of Depo-Provera injections?

Q:        How long is a woman protected when using Depo-Provera?  We have patients who frequently come in late for their shots and questions arise about when a pregnancy test is needed, when we should advise the use of Plan B and when to use a backup method.

Thank you!

A:       

 

17 weeks is the new WHO recommendation for the duration of Depo-Provera effectiveness. 

 

Depo-Provera injections are effective for 13 plus 4 weeks or 17 weeks.  Plan B might be suggested if unprotected sex happened more than 17 weeks after the last injection.  Beyond 17 weeks, backup contraception would definitely be recommended.

 

This is the most recent guidance from the World Health Organization:

  • DMPA may be provided anytime in the cycle
  • Check pregnancy test +/- and offer emergency contraception if sex after last normal menses
  • Instruct use of back-up method if necessary
  • Instruct patients to return in 12-13 weeks
  • Injections may be given earlier as needed
  • Re-injections may be provided up to 17 weeks later
  • Check pregnancy test if more than 17 weeks 0 days

 

 

FYI:  HERE ARE THE CURRENT Grady FPC Protocol Changes from Dr. Carrie Cwiak:

 

}        DMPA may be provided anytime in the cycle

         Check pregnancy test +/- offer EC if sex after last normal menses

         Instruct use of back-up method if necessary

}        Instruct patients to return in 12-13 weeks

         Injections can be given earlier as needed

}        Re-injections may be provided up to 17 weeks later

         Check pregnancy test if more than 17 weeks 0 days
