Hey there lady, WELCOME BACK!!!
I'm glad that you've gotten over being sick, sorry that you were tho... that is the pits!!!
Your AF is going to be a little different after a miscarriage because your body is "healing" itself... sloffing off & rebuilding lining, "cleaning house" if you will

so it's a good thing.
As far as at the beginning of your cycle the creamy / bloody discharge, it could also be that your cervix being partially open in the tiniest way... it's ok, my af "warned" me too that it was starting much of the same way.
