(TMI) super thick, white discharge?

I just went to the bathroom and noticed a white spot of discharge. It was thick and creamy, the spot wasn't very big but it seemed like a lot. I've never had this before except here and there when I was pregnant. According to glow today is my peak fertile day. Anyone else experience this close to ovulation or implantation if I already ovulated? I don't use opk's, just kind of go by the way my body feels
