Waalaikum assalam! Ish, I feel you, a few of us in my mum group went through this during pregnancy, and it's legit annoying, especially masa kerja. Honestly, most of us just carried tissues or a small towel and sucked on sweets or gum to help manage it, and it usually settles down after the first trimester or so (though ada yang drag sampai beranak jugak lol). Kitorang also noticed it got better when we drank more water and ate smaller meals, tapi the hormones tu betul-betul main peranan besar. Kalau it's really bothering you or gets worse, best la check with your doc to rule out anything else, tapi in most cases it's just a pregnancy thing that comes and goes!
