I have a small tender pain under belly button that arrived 9 days ago?

The pain isn't really bothering me....but it does feel tender and hurts when I touch or press the area or bump against it....pain seems to only be about a quarter sized area. It is not getting any worse and also not getting any better.I thought maybe into a muscle or something from stretching...but it feels more like a bruise when I touch it...at this point it's more mentally stressing me out than actual discomfort. There is no visible sign of a lump. I also noticed I have had a rumbling in my stomach,like gas or acid or hunger rumbles...I didn't have that the first 6 days of it though, only the last 3

Ask your doctor to examine the area of concern and consider getting CT and/or MRI.
