What is the color of your period the first time you get it?

Typically menstrual flow is red - because it's primarily blood, you may also see blackish coloured lumps which are pieces of the uterine lining. When your period first starts bleeding is light so it will look pink where blood mixes with discharge or brown where blood has gone brown due to it taking time to leave your body and mixing with discharge - your period may remain light like this throughout your first period, or as it gets heavier you may see more bleeding (red).
