Spotting instead of period?

Lauren • Adventuring through life with the one God made for me 💕

My period was due 7/3, and rather than start my full blown period (usually very heavy the first day), I’ve been barely spotting for 3 days. It hasn’t been enough for even a panty liner, only shows on the toilet paper SOMETIMES, and it’s a pale pink color. It also sometimes accompanied with EWCM. Any one experience this & have an idea of why?
