Tmi picture

Okay so last night after bd when I used the bathroom I saw something similar to whats in the picture when I wiped only it was a pink/brown color. Is that just fertile cm? I've never had anything that color before and I'm supposed to be in the beginning of my fertile week. I know the picture of todays cm is, but I didn't have my phone lastnight to take a picture of the pinkish brown color.
