Implantation?

Destiny
I had unprotected sex on Friday and Sunday ... Both times he finished.. Well today is Tuesday and around 3:30 am I went pee and wiped.. Was pink so I put a pad.. Woke up at 6 nothing on pad but reddish pink on toilet paper... Around 2 I went again and it was brown... Now its 4:52 and nothing... Is it to soon for implantation?
