Weird noise coming from my stomach

Ladies this is the 3rd time I hear this and I’m not sure if it’s just me or what. I felt my baby move a little and it sounded like a small popping noise, not sure how to explain it. It sounds funny but I would say kind of like when you’re playing with slime and it make a slight popping noise? The first time it happened I thought I was tripping but it’s now the 3rd time. Has this happened to anyone else? I’m 30 week btw.
