Sayang, both things ni kena check dengan doctor paediatric/OB-GYN respectively, don't wait lah, especially the brownish discharge boleh jadi banyak reasons dan baby weight tu pun perlu proper scan. Go to your clinic or hospital now untuk peace of mind, okay? A few of my mum friends pun pernah alami macam-macam during pregnancy, but setiap case lain-lain so really important to get checked properly. Jangan worry sendiri, doctor boleh advise what's best untuk you and baby. Hang in there!
