I get a stomach ache the same time of day. is this something that might be caused by stress? also, is this something i should see a doctor about?

Primary doctor first: A person with such symptoms can see her primary care doctor first (Internal Medicine or Family Medicine). The primary care doctor can do a general examination to see what might be the symptoms and the cause. Sometimes a referral to a gastroenterologist can help. A patient should write down her symptoms (when and how they began, etc...) and take them in-person to her primary care doctor.
