TMI all over the place

We went shopping yesterday and as we were getting ready to leave the store, I went to the ladies' room and saw the thing I've been dreading for weeks -- bright red blood.

Reassuring:
-- The quantity seems to be decreasing and the color fading to more brown
-- Our doctor said maybe to expect some spotting through week 10 because my ovaries are still huge and abused
-- I have had no cramps

Worrisome:
-- Definitely red, not pink
-- A couple small clots
-- Initial quantity was scary

We still have the ultrasound scheduled for Monday morning. I don't see much point in calling them earlier, on a weekend, because if it's a miscarriage I'm pretty sure there's nothing they can do.
