Normal je sayang, especially at 20 weeks lebih, baby mulai aktif gerak-gerak! A few of my mum friends said around this time mereka dah start feel quickening (like butterflies or bubbles), so your baby is probably getting stronger. Setiap baby beda rhythm dia, some are more active than others, so jangan worry kalau dia gerak banyak, that's usually a good sign. Tapi kalau you're worried about anything else ke or notice sudden changes, just mention it to your gynae next check-up, okay?
