Randomly nauseous

So I’ve been nauseous on and off since Saturday night…. Saturday night i went out with friends and we went to some bars and then i decided to eat lamb from a food truck (very bad idea). I puked up that night. But since then, I’ve been feeling nauseous on and off but especially when i lay down (like gerd but not as bad)…. I take my birth control daily and on time.

Should i be concerned? Should i take a pregnancy test?
