Alhamdulillah, itu memang normal je untuk first baby! Kebanyakan mummies baru akan rasa movements around 16-20 weeks, so you're right on track, aku pun sama, felt like butterflies at first tapi makin lama makin jelas. Lepas ni akan makin strong pulak, maybe in a few weeks you'll see your belly move macam ada alien kat dalam, haha.
