Implantation bleeding?

I’m 11DPO. AF is due Tuesday. I’ve had NO symptoms of AF showing up like I normally do (upset stomach, cramping, nothing.) yesterday I had a punching feeling in my lower L side but that’s it!! Not normal for me before AF. Hubby and I BD this morning. I laid there for about 10 mins. Went to pee and wiped to find this. Wiped 2 more times and it eventually went away. Faded from this to light pink to gone. Is it to late in my cycle to have IB?
