I've been lying down mumsnetting doing my paperwork for the last couple of hours, and have literally been burping every 20 or 30 seconds. Normally I never burp, it all comes out the other end
. I'm 24 weeks, so well past the retchy/burpy/sicky stage. I haven't had any fizzy drinks, or baked beans, cabbage or strange foods and drinks that may cause a flatulent effect. Anybody else having gas problems? Where does it come from and why is there so much of it?
