Implantation bleeding?

Brittany • I`m a 25 year old mommy of 3. Just found out my 4th blessing is on his or her way. ❤
Hey guys so I'm 9 dpo. I was 8 dpo last night when hubby and I had sex! When we were done he had some pinkish discharge on him and I looked down and wiped and there was a scant amount of blood. (Tmi) I put my finger in me and there was no more blood. I'm due for AF 10/8. I talked to another girl trying who believes it's implanation bleeding. What do yall think? I got a BFN today.
