16, female. i can feel and see a pulse in my stomach is this normal? sometimes its stronger other times its weak. no pain my boyfriend has it to.

Yes: It is normal. you are feeling the pulsation of your abdominal aorta. It can often be felt in slender young people

Normal physiology: The pulse you see and feel is your descending aorta. Depending on your body type/habitus it may be more prominent in some people than others. If you are very thin it's more noticeable. As a side note, there are people that have cardiovascular disease who may also notice this "pulsating" aorta which is an ominous signs of a possible (AAA) aortic artery aneurysm. See your PMD if u need more info.
