Alhamdulillah, bagus tu! At 20 weeks dah rasa gerak tu biasa je, especially kalau perut lebih compact ke-2 kali ni, uterus dah tau apa nak buat hehe. A few of my mum friends yang ank pertama pun kurang terasa cuz of belly padding, tapi ank ke-2 onwards lagi clear the movements, so don't worry lah about your first pregnancy experience, setiap pregnancy berbeza. Aminn, semoga semuanya berjalan lancar dan baby grows healthy!
