Abdominal Bloating...

Hi there I am Taniya age 20. I am experiencing unusually bloatedness in my belly especially in the lower abdomen. I’m not in periods nor having any cough or cold issue or any other medical conditions.. Due to the Bloating my waist size has also changed from 36-39 upto 3 inches. Now considering my weight 68 Kg’s and height 5feet 5 inches age 20. Is this a usual bodily change that I am observing in my tummy also, my navel (belly button) has deepened a bit as well. Hope someone answers and I want you people to see my abdomen to Check the reality. Please reply with whatsapp number as well.. Thanks
