Eat all day long?

So since yesterday I haven’t been feeling too well. I woke up in the middle of the night with bad acid reflux, which went away when I ate something. I got the same empty/weird feeling in my stomach this morning. That same feeling keeps on coming back throughout the day and now I just realized it seems to be every two hours. It keeps on going away after I ate something.

I’m 6 weeks pregnant today, could the weird stomach feeling/having to eat every two hours be a symptom?
