Bubbly feeling in stomach

Hi mummies! I’m 34 weeks today & this is the first time ever when I placed my hand to feel baby, I felt like bubble popping in my stomach (on the top right of my stomach to be exact). I know what it feels like when baby is stretching, moving or having hiccups but never felt this bubbly feeling before. I’m worried, is this something to worry about? What is that bubbly feeling? #advicepls #firstbaby
