Always feel "full"

I'm currently 18w5d. I always feel "full" even if I haven't eaten. Like the baby is taking up a lot of room or something LOL its a little painful for me too, especially when I (attempt to) sleep. My meals are crazy small too (1 ladle of beans, half a baked potato and not even a full corn on the cob) for my usual meals. Because I feel so darn full! Anyone else feeling bloated / full right now? 😩
