I know exactly how you are feeling!
I had a still birth on June 21 followed by a D&C. I could not wait for AF! Crazy?!?! I just really, really wanted that sign to show I was back to normal and so I could start trying again. Honestly I think it gave me something to focus on besides being sad. And after AF arrived I relaxed for a few days then I became obsessed with looking for my CM to seeing when I might be Oing.... (I have just started my 2 week wait! I'm sure I'll be testiing soon looking for that BFP!)
Well... sorry I seemed to have gotten off.... to answer your question....
AF came 33 days after my DC... you are wise to be ready... I spotted lightly for a day or two then BANG, heavy full blown AF!
Hugs!
