Sayang, keputihan memang normal during pregnancy sebab hormones naik, but the colour and texture kena observe closely, kalau mcm isi kelapa or whitish and odourless mmg okay, tapi since ini first time you're experiencing it, best check with your doctor just to be safe, especially around 25 weeks nie. A few of my mum friends had similar changes mid-pregnancy and their doctors confirmed semua okay, but better to get peace of mind la with your OB!
