Did I miscarry? TMI photo

I had this in my knickers today. I find it really strange as I've never seen that before... i was supposed to get my period yesterday and it was a bit brownish.not much at all....so i thought i will start bleeding today but instead this... did i miscarry without knowing i was pregnant ? I didnt try to get pregnant last month. Used protection. . but isnt this weird? What is it??? I tried to touch it to see what will it do and the white part separated by itself from the brown. 
Edit. Now i have some red blood
