Alah normal je lah! Honestly, setiap pregnancy tu berlainan, ada yg early labour pain start awal, ada yg sampai due date takde apa-apa. Dari a few of us mums I know, yang active macam you dengan berjalan banyak dan naik turun tangga actually tend to have easier pregnancies sebab the body is already doing its thing, so kadang labour pain tu memang takde atau gerak sikit je. Takde yang "mesti ada" pada timing tertentu, yang penting baby is moving, scan results okay, and you feel generally good, then you're doing fine! Just tonton je for any sudden changes or the actual contraction signs (like regularity, intensity increasing), and keep checking with your doc to confirm everything is on track. Enjoy the smooth ride while it lasts, lucky you!
