Oh, Laura, what a drama to have to go through. But it sounds like you were very brave. Obstetric stuff is just messy, isn't it? Try to keep your feet up and get help with DD and be very good and gentle to yourself.
(my last MC wasn't nearly as dramatic, but I had been bleeding lightly several days, then on one morning the bleeding increased a lot. But it wasn't until 6:10 that evening that I actually MC'ed, ie lost the sac. So I collected the sac and tiny placenta, put them in a clean container, and piled my girls into the minivan to go pick up my son from cross country practice. Looking back, I should have called another cross country parent to pick him up for me, but I really wasn't thinking straight. I was in bed by 7 that night, and didn't get up until the next morning)
