Pregnant after miscarriage?

Charleigh • TTC my first baby with my partner, after unfortunate miscarriage?
Is it possible to get pregnant with a month after miscarriage?
​I miscarried on the 26th - 30th it turned into like a period and i was due to start on the 21st
​I was hoping af hadnt shown because im pregnant but i just read that your period dont come normal for at least 6 weeks so does that mean no ovulation between miscarriage and next period or can you concieve straight away?
