Hi I'm 16 I was on the birth control depo up until July, ater that I've been fine the end of September came and I've had a possible menstrual but I was having pregnancy symptoms that's lasted for about 5 days than the beginning of October came(9th of october) and I was having vaginal bleeding (light) that's only lasted for 2 days after that I was fine now today I've been having light bleeding but I only can see it if I wipe myself can anybody help me ?

Unfortunately using depo provera can cause cycles to be irregular for quite sometime after the last injection.

Are you engaging in intercourse? Are using another form of birth control? If you are having intercourse, be sure to use another form of birth control every time. Keep in mind, however, that even with birth control used properly, pregnancy will be a possibility. If you think there is a possibility that you could be pregnant at this time, try a test.
