Ahhh sabar je dulu mama, 5 weeks memang belum tentu kantung nampak lagi, it's so normal, a few of my mum friends had the same experience and everything turned out perfectly fine! Doc suruh stop puasa is good advice sebab growing baby needs nutrients, jangan stress sangat k, stressing makes things harder for the body. Kantung akan nampak dalam a week or two je, just makan well, minum plenty of water, and go for that 28/4 scan with a calm heart, the fact that everything else okay tu dah good sign, amin ya Rabb
