How long after miscarriage did your period come back

Hi everyone. So I started miscarrying on the 30th of December at 5 weeks 6 days. I'm just wondering how long it takes for periods to return. With my other two losses I bled for a few weeks and about 3 weeks later got my period. I've been doing ovulation tests to see if I'm cycling but the lines are faint and a bit up and down so I'm really unsure what's going on. Tia
