Like the other have said bubs is still small and has lots of room in there to move around in there, so perfectly normal to go days without feeling any movement.

I first felt bubs really early but on & off, I have the placenta at the front as well so I didn't feel the real strong regular movements until about 25-26 weeks and before this would go days without feeling anything and would always panic something was wrong.

Now as much as I love feeling it move around in there, I also complain that I would like a break sometimes, especially as I'm trying to fall asleep at night and it does it's bit to get comfy in there too
