Hello, I have gone through your query and understand your concern. You have to understand that brown vaginal discharge is very common and it is usually a old blood retained in uterus. Here i have to mention that Missed period with Positive urine pregnancy test is the early sign of the pregnancy. Bloating sensation is common with periods and also present in number of conditions like indigestion, gastritis etc. As you have recently stopped depo shot, there may hormonal changes in your body, this could be the reason for brown discharge and bloating. So nothing to be concerned too much about this. Any way just check the Urine pregnancy test, to rule out pregnancy to avoid confusion regarding pregnancy symptoms. Hope this helps. Please write back for further queries. Wishing you good health.
