Stomach Issues

Hi! I've recently been having some stomach issues and would like some input.

Started March 1 -- Symptoms include:

Mild discomfort in stomach and upper abdomen

Hungry all the time even when I'm not

Feel like throwing up

Belching

Waking up in the night hungry yet sick

I thought it could be anxiety related, but I'm not anxious about anything. Nothing about my diet or lifestyle has changed.

If by the end of the month it hasn't cleared up, I'll make a dr appointment. Should I make an appointment sooner?
