Early Miscarriage?

What are people's thoughts on this? Early miscarriage or normal? 3rd day of brown discharge but only today has it had tissue in it. Went to docs yesterday and they said they can't do anything till I'm 6 weeks. Sorry if it's unpleasant but I just don't know what's going on.

UPDATE

so this is what I'm getting today,bright red and quite a bit of it. Every time I wipe there's more...
