TMI Pic Attached... Implantation Bleeding or AF coming 3 days early?

I am 11 DPO, we had sex on July 28 & 29th, I’ve been nauseous with light cramping the last 3 days (not usual for me at all & I am VERY regular with AF - as in its come on the 14th every month without fail for the last 6 months). I am someone who has AWFUL cramps but these are very light cramps compared to my usual AF cramps. Today, I originally started spotting (it was mainly blood in egg white CM) early afternoon (around 12-1 is when I noticed it) and as the day has gone on it has picked up, it’s still not much dropping on my liner as it is when I wipe but I’m curious as this is our first month TTC and I’m not sure what to expect because I didn’t have a single symptom with our first born other than a feeling that I needed to test!
