Can sex trigger implantation bleeding?

I’m around 9dpo. This morning when I wiped, there was the smallest tinge of pink/very light brown on the toilet paper when I wiped. Nothing else happened the rest of the day. Had sex about and hour ago (literally only like 5 pumps, hubby was close before we started having sex lol) then went to the bathroom afterwards and when I wiped, it was the same pinkish tint on the toilet paper. I know it wasn’t from the sex because as I said it wasn’t a long nor rough session. 🤔 Just curious as to what you ladies think?
