You can’t really feel the kick at week 16 yet. At most can feel some bubbles popping but might be still early. You can only feel the kick more obvious when you’re nearing to trimester 3. Your baby still has a lot of spaces in your womb now. Wait till your baby is bigger and there’s no space.. the kick can be painful.
No symptoms are normal. That’s why most mommies always say trimester 2 is a honeymoon period. Doesn’t mean you have symptoms mean you are pregnant. No such logic.
As long as your gynae didn’t flag out anything, it’s all good. Don’t worry.
