Hi, Im 16 years old. I recently started the Depo shot in December of 2012, and automatically stopped having periods. I didn t have one in January, and when February came along I didn t get my period when I normally would either. How ever last week on February 18th I started having a small, what I thought was a period. But it was very light and not the usually color my period normally is. It was almost like a brown color. It was very light bleeding .. Really it s just been spotting. But it s been 8 days now and I m still spotting. I also noticed last night a very weird and almost foul oder. I don t know what s wrong or if this is because of depo or not. I am sexually active and keep myself clean, I ve only been with one guy.
