Needs examination: Many possibilities. See you gp who may want to refer her on to obgyn or gastroenterologist.

Stomach pain: She may have issues with her gallbladder if she feels nausea with meals. Try to stay away from greasy foods and f/u with the doctor for labs and an abdominal u/s if continues. She may also have some gerd. Stay away from spicy foods and don't recline or lay down for at least 2 hrs after eating.
