Doctor

A:   Thank you for your question. It takes about 24 hours for the depo shot to be protective against pregnancy once administered. It is therefore possible for you to become pregnant within this period for this time. Since you have also received a positive pregnancy test, it is possible that you could have been impregnated. We recommend that you got o your doctor and conduct a pregnancy test to be certain of whether you are pregnant or not.
