I have been off depo for just over 2 months and still haven't had a period. I have had a lot of pregnancy symptoms but have been told that it could take between 6 months and 2 years for the depo to leave my system. I really don't think you are pregnant after such a short time of being off depo, i think it may just be your body trying to get back to normal. Although if you think you are take a test it won't hurt. Good luck with trying to conceive i know how stressful it can be
