Grainy brown discharge??? 😩🤔😱

Jin
Has anyone experienced grainy brown discharge in their first trimester?? I'm at 8 weeks and noticed this the day after my transvaginal u/s. At first I just thought maybe it was a reaction to the gel they use but I'm still seeing it after 2 days. I don't have any other symptoms, no cramping, no bleeding, and no itchiness. A Google search points to miscarriage...
