I'm not sure if this is normal or not but you definitely should be worried about being or getting pregnant, especially if your not wanting to start a family yet. For sure use another form of birth control.
thank you for your comment this morning after two days the spotting is completly gone so i will make a dr. appt because this is new to me
i always had brown spotting/discharge after coming off of the depo shot, i can range froma few months to a year for your body to be rid of the depo i honestly wouldn't recommend it to any woman as a for of bc, more a form of poison. The depo can mess up your cycles majorly some months you'll get AF then you won't then you will again it's a nightmare.
I would deffo see your doc about another form of bc if you do not want to conceive, but brown discharge is common in a lot of women
