Wa'alaikumassalam sis! 36 weeks na, alhamdulillah! Honestly, kalau perut lembik sikit kat area bawah pusat tu normal je, especially kalau you dah naturally punya belly pouch before pregnancy, itu just excess skin and fat layer on top, baby's head pun dah engaged bawah, so yang lembik tu bukan baby area. A few of my mum friends pun same situation, perut mereka tak sepadat orang lain, tapi delivery fine je and baby healthy. Tapi kalau you worried about how baby's positioned or anything else, best check dengan your gynae at your next visit ja, they can confirm everything is progressing well! Take care, you're doing great!
