Yeah im with the first post. It is more than likely gas. When pregnant (however gross it may seem) your body produces much more gas than when your not. I know my hubby jokes because i do it alot in my sleep. Also make sure that you are eating enough cause it could also be your tummy telling you its time to eat. There are a few things that you can take for gas so ask your doctor.
