Aah normal je tu, don't worry! Masa pregnant hormones kita naik, so keputihan putih susu memang common, especially first trimester, it's called leucorrhoea and it's your body's way of protecting baby. But kalau ada bau tak sedap, gatal sangat, atau warna berubah jadi kuning/hijau/kecoklatan, better check with your doctor cepat-cepat k, because that bisa jadi sign of infection.
