How long after your miscarriage did it take for AF to come back?

I had a miscarriage at 4 weeks 3 days on January 31st, and am currently waiting for my period to come back, how long do you think it will be? I technically started bleeding with the miscarriage when I should have been having my period, so would my body register that as a period, and then could I assume I would get my period around the 28 of this month like normal?
