Ayyy jangan risau sangat mama, very normal lah especially kalau ini fourth pregnancy, sometimes kita sibuk dengan anak-anak lain sampai tak perasan gerak halus baby, berbeza dengan first time kan semua we hyper-aware. A few of my mum friends experienced yang sama, especially yang dah ada banyak anak, gerak baby mereka baru obvious around 18-20 weeks tapi baby perfectly fine je. Tapi if you're really worried, just mention to your doctor at your next checkup so they can do a scan and put your mind at ease, one message, done! How are you feeling otherwise, any other symptoms that concern you?
