How many weeks along are you mama? I don't like the term "bubbles" cause it feels more like thumping from the inside if you feel movement. If baby is small in early gestation, I doubt will feel pain. As you go along you might feel funny, maybe ticklish almost as baby rolls or brushes over your walls with his hands or feet~ take care!
My friend felt pain when she first started feeling movements. Even went a&e but dr said it was baby’s movements causing it
Doesnt cause pain for me. Felt like muscle twitches or bubbles in the tummy!
don’t think it’ll cause pain.. feels more like bubbling
