Pregnancy after a miscarriage..

I was about 6 weeks when they told me there was only a gestational sac & no baby .. they scheduled me for a D&N; for that week .. but on 12/26 the miscarriage happened naturally .. My boyfriend & I are TTC again . I still haven’t got my period yet .. How long did it take after a miscarriage to conceive .. did it take months ? Or did you get pregnant right after .. ?
