Loud ass growling from my belly lol


I’m 18 weeks preggy now and I have constant gargling / growling sounds. SO LOUD. Like the ones where u gotta take a big poop or are super hungry.. except it’s neither of those things. What is it? I know it’s not the baby or nothing Bc I would think its impossible to HEAR him/ her but the looks I get when it’s happening LOL... people must think I gotta take the biggest 💩💩 is it just air from everything moving or something ?
