I'm on depo, i did have light light spotting now i'm bleeding dark brown? and i'm having pain on my left pelvic region? why is that i'm scared.

Call the prescriber: Best to have it checked out asap. I would be concerned about infection, ectopic pregnancy even with the Depo.

Depo: Abnormal bleeding, bleeding everyday to no bleeding at all, is a side effect of progesterone only contraceptives such as depo. The bleeding pattern you describe can be entirely normal on depo.

Depo: It is very common to have spotting or irregular bleeding while on Depo. Brown usually means "old blood" and is nothing concerning. The left sided pelvic pain, however would depend on how severe it is, how long you've had it. Any other associated symptoms. You may need to see your gyn if it is persistent or severe.
