A little knowledge needed if you can..

On 12/28 I had to have a surgical abortion. Im 42 and had health complications. Not that my reasons or anyone's reason matter. Anyway, before the termination my last period started Nov 6 2017. Obviously, I bled on 12/28/17. Today..I have stopped bleeding. Today being Jan 7 2017. In your experience or from what you may know, when should I expect my period? Does anyone know? Is there a way to calculate after abortion? Thank you for your time.
