Wa'alaikum assalam! Jangan risau sangat lah, setiap orang pregnant tu beda-beda, ada yang sakit payudara dari awal, ada yang tak langsung, sama je normal nye. Mual-mual pun kadang-kadang datang hilang, or some moms memang tak kena langsung, especially after the first trimester starts picking up. A few of my mum friends cerita yang symptoms mereka jadi kurang intense around that time, so bukan sign yang bad. Tapi kalau you're feeling uncertain or just want peace of mind, best jugalah check with your gynae at the next appointment or do a quick call to confirm, they can reassure you proper and maybe do a scan kalau perlu.
