i got the depo shot one time and i decided a couple weeks after the shot that i didn’t want to be on BC so i didn’t get my second shot but ever since i skipped the second shot, i’ve been having like brown and red discharge and this week it’s jus been like couple shades of red so i thought i must be starting my period but then the color changed again to red and brown then a mixture of both and i’ve taken two pregnancy tests and they both came back negative.
