Period after miscarriage?

Alicia

I miscarried on 6/23 at 6 weeks. I still haven’t gotten a period since then. I assumed my body would treat the miscarriage like a period because it was so early and my period would show again 4 weeks later which was this last weekend, but it hasn’t shown. We have had sex but I have been sick and on antibiotics so I don’t know if my system is just off. How long after your miscarriage did you have a period?
