TMI PICTURE

So three days past ovulation, I noticed my boobs were tender and I looked at my right nipple after my shower and noticed a blue vein next to it that was really dark. That's been going on for three days now. Yesterday I wiped and saw pink discharge. I didn't think it was a big deal until last night when I started spotting, I don't know why I would be spotting right now. Af isn't due until the 28th. Opinions please..
