Hemmorhoids after pregnancy

Are hemmorhoids normal after pregnancy even if i had a c section? I’m 3 months postpartum now and every time i poop it feels like a sharp, stabbing pain and when i wipe it’s bright red blood. I have bad health anxiety so idk if it’s hemmorhoids or if i could possibly have anal cancer even though i’m only 20. So anxious and unsure if hemmorhoids resolve on their own
