Implantation bleeding🤔

Yesterday after work i went to pee and before i flushed i noticed a small “blob” in the toilet that was around 1/2 an inch and the color was a dark blood , could that have been implantation bleeding? I was 6dpo yesterday! , i remember having implantation bleeding from my first pregnancy but it was when i wiped and not when i peed! AF due in exactly a week! Also i haven’t had anything else come out since then! I drink alottt of water throughout the day and it stood out a lot
