IMPLANTATION?? [PICS]

So I’m in my TWW and I went to the restroom and when I wiped I saw the tiniest bit of blood. I was confused so I wiped again and I got a very small amount of blood mixed with cm. According to my calculations I don’t think im far enough along in my TWW to see implantation bleeding unless my timing is off! Input would be great. I BD on the first day of my fertile window which was 8 days ago but idk if that counts ! I’ll insert pictures!

SN : My nipples

are slightly tender nothing major though and for 2 days I was having fullness in my uterus area and slight cramps
