Implantation bleeding or just rough sex

So I am 5dpo, I noticed when I wipe I have some pink spots on my tissue nothing major. Af not due till 11 days. I’m having some what cramping no other issues. I did have really rough sex last night and this morning. I guess it can be either. 🤞🏽 that it’s not just af showing. I guess my question to you ladies is can implantation bleeding be at 5dpo? Or is that too soon?
