Wa'alaikumassalam ibu! Ay, many of us mamas at that stage feel random aches and pains, growing baby puts pressure everywhere lor, so sujud pain on one side is quite common actually, bukan unusual. But since you're already 8 weeks 6 days and it's bothering you, best check with your gynae just to be safe and get their peace of mind, especially anything pregnancy-related kena confirm with doctor je, okay? Take care of yourself!
