Do other people have blood when floss too? Is that normal? And what should I do if it’s not normal

the first time you floss after not doing it for a while, yes there's definitely going to be bleeding. But if you still have bleeding gums after a week of brushing and flossing, then I would go see your dentist you might have gum disease.

As far as I know, bleeding from flossing is a sign of plaque and sensitive gums. Flossing used to be uncomfortable for me too, at times resulting in bleeding. But as I began flossing regularly (once a day), the sensitivity went away and my gums don't bleed anymore. Essentially,
flossing keeps your gums healthy and clean. If you continue to bleed for an extended period of time, you should talk to your dentist.
