Completely normal, don't worry! Pada 10 weeks, baby movements kadang-kadang je terasa, especially kalau first pregnancy, some of my mum friends didn't feel consistent movements until 16-18 weeks. The placenta position and where your baby is positioned inside juga affect how much you feel, so some days active, some days tenang je is totally expected at this stage. Kalau ada any concerns or just want reassurance, mention it to your doctor at your next checkup, tapi honestly this is par for the course!
