Discharge brown to pink no pain

Hi ladies im looking for some opinions.. 2 days ago when i wipe myself it was brown yesterday nothing and now its light pink and some red i had a miscarriage back in August and that was my second miscarriage so im on edge about everything but i have my first appointment Tuesday.. should i go to ER or just wait til my appointment appt will just be paperwork) i have no cramping or anything but still so scared and if i wait til Tuesday maybe I' just express my concerns to them?
