If you really were bleeding that much I suggest making some phonecalls, you're in ontiario so have you ever heard of telehealth , if you'd like I'll pm you the number.
I had a lot of bleeding during my pregnancy.. everything was always fine , but I never bled that much at one time.
I always had to go to the hospital when I bled because I'm rh- , so they would always do a good check and NST to make sure everythign was alright.
I hope all goes well at your appointemnt
