I know what you mean, and it sounds like a tiny knuckle cracking, or like a rubberband snapping. I am 36 weeks and this is my second pregnancy, this is definantly not just a kick. I am trying to find info on it as well...
I think its little kicks :)
It feels like popcorn popping... like leighanne143 said...
Its probably a little kick. Does it feel like a light tap?
that s funny because when i first started to feel my little ones movements i said it felt like popcorn popping in my belly.
That's probably a little kick.
