Really Bloated

Just got my first + on Monday! I’m about 3.5 weeks along according to my HcG levels. I haven’t been pregnant in 3 years. I have almost 3yo twin boys. A few days ago, my cravings (or what seems like cravings) kicked in and it’s all salty stuff. Unfortunately, I’ve given into those cravings. I’m really really bloated. I’m having regular BMs, burping and passing gas, and regularly urinating. But my stomach looks like a balloon and feels full, even when I’m hungry. I’ve been drinking plenty of fluids like water and juice but eating lots of salty foods. I took 4 capsules of gas x yesterday and it really didn’t bring any relief. Is this bloating relatively common or do I need to seek medical help? TIA!
