Second trimester baby bump

Very common for 1st time mums. You'll not feel any baby's movements until a later stage though some might have felt at 17th week or so. But you'll still feel some flutters, bubbles or poppings in your tummy. For subsequent mums, we feel it earlier. I felt mine at the 10th week. Also, your bump is smaller as it's your 1st pregnancy. That means your uterus has just started to stretch with this pregnancy. Your bump will be bigger with your subsequent pregnancies. And also do note that all bumps are different in sizes and there is nothing to worry about as long as your baby is growing well & healthy inside.
