TMI warning!

Hi girls, I’ve not had a period for over 2 years. It hasn’t been investigated because of my weight. I have had my ovaries checked and everything seemed ok.. However for 4 days I’ve been bleeding lightly mainly light brown and pink in colour but have had some red too. Pic of the colour.. would you consider this to be a period or maybe something else? *FYI I’ve had regularly smears and I’m not on birth control*
