Menstruation while Breastfeeding

Hi mga momsh, Ask ko lng sa mga breastfeeding mommies, gaano katagal kayo nagkaron o bumalik menstruation nyo? I'm just concern dahil 5 months na si baby, nagkaron ako ngaun but I'm still not sure kung menstruation na to, I'll still have to wait for the next month to check kung magkakaron ulit aq. #1stimemom #pleasehelp #advicepls
