Eh jangan risau sangat lah! Keputihan campur lendir kuning yang keluar malam je biasa je during pregnancy, especially kalau tak ada bau atau gatal, that's actually your body doing its thing to protect baby. A few of my mum friends experienced the same thing, mostly towards the end of pregnancy, and semua okay je. Tapi sebab ni second pregnancy for you, maybe best check with your doctor or midwife next visit just to be sure, especially since you're being extra cautious, they can do a quick swab kalau perlu and beri you peace of mind!
