Ahhh I've heard a few mums mention this during pregnancy, especially around your weeks, bisa jadi dari stretching of ligaments ke sebelah, or memang the way baby is positioned tu pressing on that side! But honestly, sakit yang tak hilang and affecting how you move, especially first time you experience it, better check with your doctor just to be safe kan, sebab they can proper assess if it's round ligament pain or something else. Mee goreng tu unlikely la (though heavy food memang boleh trigger gas), tapi the sudden onset with position sensitivity is worth getting checked out, pregnant bellies senang je trigger false alarms tapi better peace of mind! Jangan lagi lie on that side if it hurts; try the other side or semi-reclined position dulu. How's it feeling now?
