I feel for you, I've been the same.
Only started having heartburn or acid indigestion recently, but the whole pregnancy I've had tonnes of wind and been burping loads. Some days it drives me crazy lol.
A couple of times I've found I have got constipated and suffered worse, like I'm backed up lol.
So for the last week or so I've been eating smaller meals and buying more fruit, less veg, and stuff like cucumber, hummus, pitta bread, bagels etc (as snacking is better than having huge meals especially on an evening). I've also had porridge a few evenings for my dinner, and I've been buying packs of prunes from Sainsburys and finishing a bag in two or three days lol.
