My last depo shot was in late August, I still haven't started my period. I have all of the pregnancy symptoms, is it possible that I am pregnant?

It is possible althoug its very unlikely. There is always that .1% chance or what ever your shot is. They are all different, some stranger then others and the only 100% birth control is no sex. So its possible for you to be pregnant but if this is a new shot it may cause you to not have a period but a certain time or the year. Call and ask your dr.

Yes, it is possible. Have you tried a pregnancy test? You are considered no longer protected after about the 14th week from the last injection. It is not unusual for you to have no period or irregular periods for awhile still.

If you are not using another form of birth control, and are trying to become pregnant, you may want to try a test once a month to check for possible pregnancy since you can't use the lack of a period as a possible sign just yet.
