Indigestion?

Does anyone else get indigestion or know what causes it? I’m 15 & occasionally usually when I go out for dinner or something I’ll get indigestion (or at least that’s what I think it is). Basically when I get it I get a little pressure in my upper stomach and lower chest, I get bloated & my chest will make gurgling noises. I’ve had it for a couple years. It feels a lot better when I lay down and relax my body. Does this sound like I should be worried? Do u get this ever? Is this actually what indigestion is? Cause I’m guessing
