26 days of bleeding ):

wo

I have an appointment for the absence of my period next week since I didn’t have my period since September but for 26 days now i started to spot at the beginning and it was super gross black old blood and now for the past week it’s mostly all red and heavyish (some black) with decent size clots and I feel sick... should I go to the hospital before the appointment since I’ve been bleeding so much?? /:
