Conceiving after stillbirth

How long did it take you to fall pregnant after having a stillborn? My first son was born on 3rd February 18 at 24 weeks 5 days, for some reason he stopped growing at 21 weeks.

I know after something like this everyone has different grieving, some people fall pregnant quickly and others sometimes decide to stop ttc! I’m just wondering how long everyone waited till they conceived again? I’m currently 4 weeks pregnant with our rainbow baby
