hi I've woke up with the strangest noises coming from the top and sides of my bump, it sounds like air bubbling though water but a lot of it. A bit of a random description but like when you squeeze a water bottle with a sports lid and then the air rushes back in. i called the midwife and she told me eat something and call back later if it doesn't settle down. Has anyone else had this? Or knows why it happens? Is it because things are about to get going?
