I have had the same problem since about 7 weeks or so. I'm 13 weeks now. It's so bad that when I wake up I look normal and have a flat stomach and by the end of the day my belly looks 6 months pregnant (no exaggeration!) and it feels soooooo uncomfortable. I drink a ton of water, I take probiotics and drink apple cider vinegar, eat fiber, I take miralax almost every other day to combat constipation, and I try to eat small meals instead of big ones. None of it helps. I even limit my gluten intake and I'm already lactose intolerant so I don't eat dairy. It's just so bad! I'm going to ask my dr what to do when I go there next week. If you figure out the solution let me know! Good luck! :)
