Blood in stool

For the past couple of days, I have been noticing a good amount of blood in my poop. I have been feeling fine, but I also have been having nausea, and stomach pains, just brushing it off as anxiety. I’m home from college for the weekend and I want to tell my mom, just to see if she thinks I need to go to the ER or call the dr. I’m scared and everything time I think about telling her I start crying because I’m really nervous. How do I tell her?
