Eh jangan worry sangat, quite a few of my mum friends pun kena sama situation masa pregnant dulu, baby measuring small is so common and doesn't always mean ada problem, banyak baby yang catch up dalam 2-3 minggu je! The repeat scan in 2 weeks is exactly what doctor should do, so you're in good hands and that's actually reassuring. First pregnancy memang scary, tapi most of the time these things sort themselves out, just make sure you eat well, rest, and go for that follow-up scan okay? Take a deep breath, you're doing fine!
