Unsure when to expect AF after stopping BC midcycle

Devin
Hello...I stopped my BC midcycle and now have no idea when to expect AF. I had my traditional AF 12/16 -12/17. I stopped my BC 12/23 and had withdrawal bleed 12/25 - 12/28. I have no idea when to expect AF so therefore have no idea when to test. My 11 yo was an oopsie so actually TTC is driving me nuts lol.
