I'm 18 years old and I used to be on the depo shot, I had a brown discharge from my vagina, after having sex, I bleed a little from my vagina. Help? Anything I should be concerned about?

See G.Y.N.doctor. Having little brown discharge and bleed after sex could be due to friction /trauma, it may stop in a day or so. But if continues see G.Y.N.doctor, get checked for any ulceration or infection - to rule out for sexually transmitted diseases.
