Pink after sex on 12 DPO

I’m 13 DPO today and last night was 12 DPO and we had sex. Has anyone ever experienced pink CM after sex? In my years and years of having sex I’ve never ever bled once (not even the first time) and we did not have rough sex at all.

There was no red at all, no brown, just the lightest shade of pink and no bleeding since. Also ZERO cramping.

Thoughts? I tested today and it was negative I think but I only did it on a 3 hour hold. I have this problem where I pee a bunch in the middle of the night so even tho it was FMU it was only have a 3 hour hold.

I know the easy answer is to just test again tomorrow :)
