What's the latest dpo of getting a positive

What's the latest implantation can happen or a positive pregnancy test? Im 2 days late just waiting for Af but I don't feel shes coming yet and I'd rather her just come so I can try again. But hey maybe I'm pregnant. Doubt it since I took a test on Thursday. I've had sore boobs for 2 weeks already. Just wondering 😉
