Wa'alaikumassalam! Itu normal je, baby active malam tu common around your stage, mine pun camtu, lagi terasa when we're resting kan, so gerakan dia lebih obvious. A few of us from my mum group yang due around the same time all noticed their babies jadi lebih active at night, maybe sebab dia tidur siang-siang je hehe. Make sure you're tracking movements and staying hydrated, tapi honestly sounds like everything is progressing fine! How many weeks are you now?
