Period after D and C

Ta
Hey. I am just wondering when women who have had a D and C got their first period after.  I had a D and C May 26 and was on antibiotics for an infection and heavy bleeding following the procedure.  I've had no signs of a period.  I tried using the app based on the last day I bled after the procedure.  But according to the app it should have been four days ago.  
Just wondering when to expect it!? 
Thank you in advance
