5 months postpartum and no cycle

welp, 5 months PP as of yesterday and still no cycle. EBF with 1-2 over night feeds. with my last baby I didn’t get a cycle back until 10months PP but for some reason I thought my body would be less sensitive to prolactin the 2nd time around and I would be cycling by now. i want to get pregnant this fall before Christmas but obviously won’t be able to without a return to period. without weaning my baby does anybody have tips on how to bring about a cycle while nursing?
