I'm in Week 21 now and started feeling the movement in Week 18. It felt like some sort of fluttering at first and now I would describe it as little pounding (not painful). But however, since week 20/21, at times I could feel the sides of my belly distinctly feel aches/ a little pain esp as I toss in bed (not with the bb movement I feel)... FTM here btw :)
It felt like tiny little bubbles popping inside me at first and I thought that it was just gas.. it will get stronger as the weeks go by and you’ll definitely recognise it. Baby’s movements and gas actually feel different.
felt like little pounding and waves for me. yes it’s normal
yes, it's totally normal. enjoy the movement! :)
