worried about my poop

I don't really have money to go to a doctor right now but I my sister told me that she learned in a class she had to take that tan poop meant something wrong was going on in your digestive tract somewhere and the past couple days my poop has been tan. Nothing that I've read online can seem to give me a clear answer on what it might be I just want to know if you all think it's serious or not? It's like a tan color and looks like soft serve consistency. I'm really worried but I know that worrying and adding stress to myself would likely just make any potential health problem worse. I don't even have like a family doctor or anything I don't really know what to do.
