Haha I totally feel you, memang serik after bersalin! Honestly masa nifas habis tu belum tentu fertile lagi, sebab cycle kau still adjusting especially kalau breastfeeding (boleh delay ovulation berjam-jam lagi). A few of us tried tracking lepas nifas and it took like 1-2 months lagi before proper cycle balik, so safer to start counting from first proper period after nifas habis then use the usual ways, either count 14 days dari first day of period (kalau cycle regular), or use ovulation tests, or track cervical mucus changes (jem jem transparent macam egg white tu sign subur). If breastfeeding full-time, lactational amenorrhea boleh protect you for a few months pa, but once you start mixing feeds better track properly la because hormones dah berubah.
