Is this IBS ?

Hi,im in my 20 and for the past months ive had this bloated feeling in my stomach, like theres so much gas in it and it tends to make my upper abdomen hurt if i cant get it out soon (which is frequently happen). i also feel difference in frequency and consistency of my BM (more freq, tend to loose). Ive gone to the doctor, told my stories, and he said that its okay even before the physical exam. After doing some auscultation he said everythings fine and maybe theres something wrong with what i eat (eating something too spicy etc) and just to improve my eating habit. I feel relieved (mentally) after that but my symptom sometimes came back and im not quite sure that im "okay". Im not sure whether just doing physical exam without lab test is adequate to rule out my condition. Is this some kind of IBS or should i go to another gastroenterologist and ask for some lab tests?
