When will I get my AF after MC?

Hi ladies, hope you can advise?
I had a missed MC 40 days ago and still no sign of AF? I have no period symptoms (bloating, sore boobs etc..) And I took a pregnancy test this morning to check but negative. Really worried! Anyone else experienced the same thing? Thanks x
