Breastfeeding 23months old and trying to get pregnant

I am not sure if you are the right person to ask but I am trying to get pregnant but my period hasnt came back but for one cycle in May, no periods since then and since Magdalene was born two years ago.

I dont want to stop breastfeeding her but I want to get pregnant soon. I am not sure what to do. Should I let nature take care of this decision or try to help Magdalene wean a bit. I ve been trying to wean her off during the day n nurse her at nights in hope of getting my periods.
