freaking out...advice please

Hi, so i am 6 weeks 4 days today...I have had really bad gas for the past few days...I feel bloated and feel some kind of pressure on my abdomen, even as I walk...no bleeding or spotting (thank God), just a lot of discomfort in abdominal area..its not cramping either, i do feel some pain at times but it feels like the pain you get when you have too much gas...especially when i lie down...then I feel some emptiness in my stomach...is all this normal? should i go to er? i think im also a bit anxious as i will be flying out tomorrow and this is all making me worry too much 😞
