Me too!!!!!!!!!!!!!!! For days this was my one real symptom (okay, tired and hungry, but whatever). No change in diet. And they hardly list it at all in those catalogues of early pregnancy symptoms, which made me feel somewhat left out. Hooray for us all havign gas, LOL!
I'm going to weigh in on this one too. I thought that I was going to explode yesterday--can't imagine how I would have felt if it wasn't passing as much as it was (tmi, i know, but, wow!). I found that knee chest position helped as did going for a long walk (alone, in an unpopulated area!).
Knee chest position is a great position for lots of things preg related. Start on your hands and knees (all-fours) then lower your upper body down onto the floor/ your knees (yes, so that your rear is in the air). Rocking back and forth between all-fours and knee chest helped too!
Good luck! I am full of sympathy (and gas, too!)
