Aww mama, at 32 weeks that bloated, tight feeling is so common, baby is getting big and everything inside is squished! Try eating smaller, more frequent meals instead of big ones, drink lots of water, and walk around gently to help with digestion and that heavy feeling. The side-sleeping discomfort is real too; try propping yourself with pillows on both sides so you're not fully on one hip, and change positions every hour or so. But since you're experiencing persistent tightness in your belly and lower back pain, do check with your gynae just to make sure everything is okay, better safe than sorry at this stage, especially if the discomfort is affecting your sleep and movement. Hang in there, you're so close to the finish line!
