Miscarriage is this normal?

Warning: kind of gross.

I found out that I was going to miscarry yesterday. I would have been 6 weeks today. I began spotting last night and passing blood clots. I expected to wake up to heavy bleeding like usual, but it's been 24 hours since spotting started and it hasn't picked up at all. But the weird thing is I am passing clumps of tissue every time I use the restroom. I've always had heavy bleeds with miscarriages so I was wondering if I should be worried. Just not normal for me.
