Waalaikumassalam! Congrats on your baby, mama! Honestly, timing macam ni boleh confusing, lochia (darah nifas) boleh berhenti then start lagi if you overdo things, or memang haid dah datang balik. Since you're exclusively breastfeeding or not, that also affects when haid comes back. Best thing is jangan risau sendiri, go see your doctor or midwife to confirm okay, sebab they can check properly, especially if ada mual dengan darah keluar, better safe than sorry. Moms dalam group saya ada yang haid balik 6 minggu, ada yang delayed, so memang vary dari person to person!
