Aihhh sayang, ini memang boleh jadi confusing! Tapi honestly, kalau scan dah confirm 1 bulan lebih, then that's your actual dates lah, UPT je sometimes still negative pagi-pagi even if pregnant, atau timing je off. Perut kembung tu very normal dah especially if second baby ke, atau just gas and bloating je. Tapi since you're concerned, best to check in with your gynae lagi sekali, dia boleh confirm everything is progressing well and ease your mind, okay? Jangan stress sangat lah, a few of my mum friends pun pernah macam ni and everything turned out fine.
