Assalamualaikum.

Wa'alaikumsalam sis! Ohhh I understand the worry lah, first baby memang buat kita overthink everything! But honestly, baby weight at 36 weeks varies so much from baby to baby, and kita cannot judge dari ultrasound estimate je (those numbers boleh berubah-ubah). The thing is, I'm not trained to say if yours is ok or not, so please check with your doctor at your next appointment or call the clinic , they can see the full picture and rule out anything that needs attention, ya? My few mum friends also had babies with different weight estimates, and most turned out just fine, but some needed closer monitoring, so better safe than sorry! Don't stress too much in the meantime (easier said than done, I know ), tapi do get checked out properly, ok? Wishing you and baby all the best! You're so close to meeting your little one
