Alah, 11 minggu tu memang cepat sikit but totally normal lah especially anak ketiga, your uterus dah stretched dari pregnancies sebelum tu, so you recognize the movements faster! A few of my mum friends swear that dengan anak second atau third, they felt movements way earlier compared to first time, sometimes even 10-11 weeks. Takpayah worry, it just means you're more tuned in to your body now. Tp best jugak you check with your doctor just to confirm everything is on track okay
