Sayang, jangan risau sangat dulu, doc dah aware dan tengok kan dia regularly, tu yang penting. Berat baby berbeza dalam kembar tu memang boleh jadi, tapi since doc dah mention about the blood flow difference, kena follow his/her monitoring plan closely je dari sini sampai deliver. A few of my mum friends with twins cakap the anxiety is real, but staying on top of appointments and scans really membantu ease the mind. You're doing great by being proactive about this. Anything yang terasa off or worried, jangan tunggu appointment, call your doctor okay?
