*********TMI********* 5 weeks and weird discharge?

Yesenia
So im about 5 weeks i went to the ER sunday night because i started bleeding red it stopped at the er and they said everything looked fine, but id have to wait because they couldnt really see anything since im so early. Since monday ive been having this white discharge with weird brown dots in it. Is this just old blood still mixing in and coming out? Or could it be a miscarriage?
 Any ideas?
