Eh congratulations on your first! Aah tu memang early quickening, some mums feel it around 15-16 weeks especially if baby's position is low or if your placenta's at the back, so u're not imagining it! The mencuit-mencuit sensation is legit baby movements, especially since scan confirmed kaki dia kat situ; a few of us tried keeping a kick count diary from this point just to get familiar with baby's pattern (helpful later when u need to monitor). So ya, that's your little one saying hi!
