Uncomfortable after I eat

My belly feels super full and stretched out no mater what or how much I eat or drink. I’ve tried smaller snacks instead of meals and nothing seems to help. I had a little bowl of popcorn the other day and instantly felt uncomfortable and bloated & nauseous. But it’s been happening everyday for almost a week.. Is this just common because the baby is growing? Any ways I can get comfortable? I just keep switching from laying on my left side to my right and hoping it helps.
