Abdomen pulsation. Related to heart)

Is it normal to feel pulsation in abdomen, such strong that mywhole abdomen is moving with it, and i am not a thin guy, i have waist of 42 inches, i have just discovered 15 days back is it normal or should i get tested , it feel strong while lying on bed, some days back had my echo, ecg chest x ray done everything was normal... I am suspecting abdominal aortic aneurysm, because one of my friend had it, and thats giving me anxiety had consulted cardiologist as well, but all they said that its palpitations but i can feel them whole day when i am anxious or not, ye but anxiety make them more visible my whole abdomen moves with it, also i can feel my heart throbbing in left side of chest, also i had chest pain (not related to heart)
