Light pink spotting 6mo PP, EBF?

I’m exclusively breastfeeding on-demand & bedsharing with my 6 month old. My husband and I have DTD several times since baby was born, and there’s never been any bleeding/spotting & no first PP AF yet.

We DTD last night & when I went to pee right after, there was just a very small (almost missed it) amount of light pink blood when wiping. No more 10 mins later when I went to the bathroom again. Nothing was painful or gave any indication of anything causing bleeding.

What is this? Ovulation (I’ve never had spotting with ovulation in the past though), first PP AF on the way, just random? So confused.
