TMI Miscarriage?

TMI, I have had multiple positive pregnancy tests including a digital. Just this week though. I’m now bleeding a lot and have clots. Would it be safe to say this is an early miscarriage? I’ve never been in this situation before. Do you just play it out? Or is this something that needs to be seen by a doctor? I do have an appointment mid next week, which was going to be to confirm the pregnancy.
