Hi. I Have A Urgent Question About Pregnancy Or That

Hi. I have a urgent question about pregnancy or that could be a early miscarriage. My period were delayed by 5 days at first and only for a duration of 2 days instead of 6 days like normal. Now I reached my 2nd period and noticed after day one that the colour of my menstruation was a light pink colour. On the second day there were some red blood and some form of a darker red clot on my pad. As I stood up from the toilet I saw something unusual. It looked like some type of mucus with a light red and white combination colour. Almost slimy looking. I just want to know what it could be and if I need to see a doctor.
