I had my period on July 16th, almost 2 weeks ago. Starting last night, I am now having brown discharge. Not only when I wipe, it's enough to be on my underwear as well. It has an odor but not one I can really describe. I am asking what it is because its not close to my last period or to my next one so I don't know why it would be random excess blood. I took a pregnancy test and it's negative. Can anyone help as to what's going on?
