Hiii, at 12 weeks 5 days memang boleh start nampak sikit but honestly lagi banyak bloating dan perut tegang je, bukan fully baby bump yet, most of us didn't see obvious bump until 14-16 weeks! Kalau you buncit before pregnancy memang harder nak notice, tapi if it's tighter or fuller than usual around the abdomen area tu likely combination of baby, gas, and hormones doing their thing. The way to know is if it's firm and high (baby) versus soft and squishy (bloating), so press gently and see how it feels lah!
