Super tight & bloated tummy after meal

Currently in 3rd trim, with a big belly. Hate it whenever after eating, especially after dinner, my tummy will become super bloated, hard, and tight despite eating moderately. It will become very tight and super uncomfortable to the point sometimes i feel breathless and its impossible to sleep and all positions, including sitting is very uncomfortable. I would usually just spam yuyee oil for short term relieve for few times. Any tips to lessen the uncomfortable feeling after eating? I tried to walk around the house for few mins and feel even more uncomfortable due to the weight of my belly. #FTM
