Aduh, better check with your doctor cepat-cepat lah, sayang, keputihan kuning especially when you're pregnant boleh jadi sign of infection macam bacterial vaginosis or thrush, and kita kena make sure baby okay je. A few of my mum friends kena the same thing during pregnancy, and doc cepat-cepat prescribe antibiotics yang safe, so jangan worry sangat tapi do get it checked soon, okay? Kesian kalau delay-delay nanti.
