Eh, gas during pregnancy memang la very common, especially around your stage! A few of us mummies found that eating smaller meals more often, staying hydrated, and moving around (even just walking) really helps, constipation makes the bloating worse, so that's why you're feeling so uncomfortable. Try to avoid carbonated drinks and foods that cause gas like beans or fried stuff, and maybe do some gentle stretches or yoga poses for pregnancy, those help shift things along nicely!
