Hello, I'm nearly 27 weeks' pregnant and feel as though I'm on a plane most of the time - my ears are permanently 'popping' (like when you're on a plane, or about to faint) so I can't hear myself (or anyone else!) speak properly. And I'm feeling really sick and tired. Does this sound normal to you? Am sleeping really badly, so that's probably not helping. Meanwhile baby happily kicking away! THanks for any advice
