TMI PICTURES!!! Miscarriage at 6 weeks Is passing these tissues normal?

I have been losing large blood clots and tissue like these non-stop plus heavy bleeding for 3 days. Im not sure what any of these tissues are or if they are normal. It started with large blood clots (1st picture) I was passing blood clots like these Once every hour for half a day, ( plus second picture) and then (3rd picture) passed right after peeing, I was passing tissue similar to this every time right after peeing, then found (4th picture) this had passed the next day after heavy flow bleeding ( i was filling up a pad every 2 hours) I have not passed any large tissue or clots since the last picture ( this morning) i have just had medium flow bleeding on and off. is this normal? What are these tissues/clots? I would really like to know what they are

- I have not seen a doctor yet.
