Sayang, keputihan macam tepung basah tu biasanya fungal infection (candida), especially kalau ada muntah teruk, pregnancy hormones and nausea boleh trigger ja. A few of my mum friends had the same thing and doc suggest dierang kena ambik antifungal cream or pessaries, bukan antibiotic ja. Since dah tried ubat 2 kali and still ada, better ambik that sample test your doc mentioned so dia tahu exactly what type of infection and give the right treatment, sometimes kena switch to different medication kalau the first one tak effective. Jangan worry, it's actually quite common in pregnancy, but do follow up dengan doc ye!
