Yes it is normal. The fact is all your organs are moved up and squished together! Not only that your skin is being stretched tight over both baby and organs! Up your water intake so there is plenty of fluids for the organs to move around in! It will create more of a cushion for them when they bumpin off of your baby and other organs! If it continues after upping the water contact your doctor to have it checked out! Pregnancy hormones speed up the development of both gall stones and kidney stones and this will also cause pain in admonal area!
Also when I breath in it also hurts!
