When can I expect AF?

Morgan
Hey ladies! I had a chemical pregnancy mid October and I was curious if anyone could tell me around about how long it should be before my next period? I still haven't had one since then and I have no symptoms of starting anytime soon.. I got a positive ovulation test two weeks after my chemical but still no AF. I tested around when glow said I should have AF but it was a BFN. I'm on cycle day 41 now.
