Should I go to the doctor anyway?

Okay so super weird and embarrassing question.... So there is red blood in my stool. I thought it was blood from my period cuz I've been off it for 2 days. But when I wipe it's not from my vagina. I saw lots of red in the toilet this morning but brushed it off. Now I look and see it's definitely from my stool. But also.... I have a weird habit of eating the shell on sunflower seeds and I've eaten a lot of them the past 2 days. So.... Do you think it's from the sunflower seed shells or should I go to the doctor, or go regardless....??
