Light pink CM. Am I past IB timing?

Kira • TTC 1st for 15mons and I finally had my BFP!

So tonight I noticed a super light pink discharge when I wiped after BD. After I cleaned up I noticed some on our bed as well. The BD wasn’t exceptionally rough, and discharge stopped after 30 minutes or so. I’ve never experienced this before.

I’m 11dpo, what could this be? I’m assuming not implantation because I’m past that point. 🤔 Is it an early pregnancy sign?
