Eh, 8 days postpartum discharge benda normal lah, especially kalau takda bau and takda sakit, sounds like lochia aje yang slowly changing colour as your body heals, tapi since even the nurse tak sure better ask your gynae or check back with the hospital just to be 100% sure, ya? A few of my mum friends had yellowish lochia around that time and it cleared up fine, but honestly paling baik check with doctor kali ni just for peace of mind sebab luka masih fresh lagi.
