When massaging gas while pregnant, it is important to ensure that you use the correct technique. To begin, find a comfortable position and place your hands on either side of your stomach. Gently massage in circular motions using light pressure, working up from right below the rib cage and going slightly above your navel. Make sure not to press too hard or too deep as this can cause discomfort for both yourself and baby! Additionally, be mindful of not pressing directly over any visible veins or arteries which could result in reduced oxygen supply for baby. Finally, listen to your body; if you experience any pain or discomfort during the massage then stop immediately and speak with a healthcare professional about alternative methods.
