Pink spotting?

Ashley • Blessed with 2 boys. One angel baby Ryker and one 2 year old Troy. Trying for a Scarlett.

So ladies. I ovulated maybe 5-8 days ago. By saying maybe, I had A LOT of pink EWCM on my 14CD and a positive OPK on my 16. Today I checked my cervix and mucus and it was pink. Not much spotting but enough to notice. Thoughts on what this is? I'm on 21CD if that means anything.
