Help please!

I'm not pregnant! But I have these uncomfortable feeling in my stomach. To my upper stomach to my lower admoninal. It stays for couple of hours? It's not painful but it's there? Idk how to explain the feeling. Has anyone had this before? I've had these feelings for awhile. 10 / 11 weeks ago I had a flu/ cold were I'd have a bad cough and it turned to me finding it harder to breathe but I still could breathe, that went away. either way I've had these stomach weird feeling and idk what it is. Going to the doctors this week. If anyone could help me out for the time been that would be awesome!! Thank you xoxo
