They coughed up blood.

Wait what-

I think that's normal. Im not 100% sure tho.

And after I was done brushing my teeth I kept spitting blood into the sink. I just rinsed it down the sink and drank some water and then I was okay.

have you been brushing your teeth normally? If not, It's probably your gums bleeding

I brush my teeth two times almost every day.

However, every time I floss I see blood. But yesterday I felt the blood coming out of my throat.
