So I've had 1 shot of the depo at the end of November I haven't bled on it but yesterday I had a brown discharge followed by spotting and since then I have been having horrible pains in my side like shooting pains in my left side, my pelvic area is so sore I took a test a week ago and was neg but still so worried?
