Did I scratch my cervix?

So, I’m 14 DPO today, AF was expected yesterday. I noticed heavy yellow CM about 3 hours ago and checked my CP. when I pulled my finger out I had brownish/pink cm on my finger. Put some toilet paper down there just in case I brought on AF accidentally (stupid me). Came back an hour later to this when I wiped?

And nothing since? Nothing on my liner, nothing in the toilet? Once I start spotting I usually spot bright red for an hour or two before AF comes in full force. Is it possible I scratched my cervix? After researching I’ve learned it very easy to irritate the cervix so I will NOT being checking CP this close to AF again but, could that possibly be the case?

Not trying to grasp at straws but, it’s just unusual for me. Once there’s spotting, blood immediately follows. I don’t think it could be IB this late? I O’d on 12/17 so it’s a bit late for IB. Hubby and I did BD about 10 hours prior to the pink/brown blood I got on my finger after checking my cervix, not sure if that had anything to do with it.

Any advice, ladies!?
