Conceiving and ovulating??? Calling those experienced!

If you conceive before your ovulation time frame, like the sperm and egg meet early in the fertility window, do you still get a lot of cm?
​Also, today is 6 days after a not so very successful withdrawal. That woad yeas day 1 of fertile window. Today a random bit of blood on tp, not brown though. I'm about 13 days away from AF Today is the end of my fertile window. Too soon for implantation?
