Sayang, you need to see your doctor or midwife asap about this, jangan delay! Baby weight at 26 weeks is something only your gynae can assess properly with your scan results and medical history, so please don't worry sendiri dulu, just go get checked out. A few of us mums have had similar concerns and it turned out fine after proper checkup, but some needed close monitoring, so penting sangat you get professional advice, okay? Take care!
