Even though Depo shots are usually scheduled 12 weeks apart, the contraceptive effect of the shot lasts 13 weeks. Find out the date of your last injection and count forward 13 weeks. If the dates of your intercourse fell before the end of the 13 weeks, you were still protected by the shot. If the dates fell after the end of the 13 weeks, you were not protected. However, even if this is the case, pregnancy is highly unlikely because of your bleeding.
Contact the medical provider who gave you your last injection to discuss how you will prevent pregnancy now. If you simply missed your shot and you would like to continue using the shot, he or she can help you restart the method. If you were unhappy with the shot, he or she can talk with you about other options. In the meantime, either abstain from sexual intercourse or use condoms from start to finish for every sexual act.
