Was that implantation bleeding?

Courtney • Married to the love of my life and trying to conceive our one baby to complete our small yet mighty happy family. ❤️
A little TMI, but my SO was giving me oral sex last night, nothing was actual "inside of me", and when I was done, I wiped up, and there were streaks of orangish pink blood in my CM that came out afterwards. It was there a good three wipes. 
​And then two hours later, I went to the bathroom, and again, the same thing! I'm 8 DPO and have also been having a stinging lower back pain for about two days and crazy emotions and light cramps right behind my pelvic bone. 
​Advice please!
