I’m mildly worried

Before u get started, I’m low-key a hypochondriac. I just threw up after a night of drinking, and want to know if: a) is the red spot blood? b) are the brown spots still? Keep in mind, I also ate a small slice of cake with caramel which could contribute to the brown spot’s color. I know I’m probably freaking out for no reason, but I want to know what y’all’s opinions are on this
