Wa'alaikum assalam! Okay lah dear, keputihan tu memang normal during pregnancy sebab hormonal changes, tapi yang berwarna kuning macam tu, even kalau tak berbau atau gatal, kena check dengan doctor yer. Tak payah risau sangat, but better safe than sorry when you're 7 months pregnant! Aku ada few mum friends yang similar situation, and doktor just need to make sure je everything okay dengan baby. Go book your next checkup and mention it to your OB, okay?
