How soon after sex can white discharge be a pregnancy indication?

I've heard white clear discharge is a sign of pregnancy but I tend to have it a lot normally. I just never keep track of my cycles. Don't really care for it. So how soon after sex can it be a pregnancy sign? Just trying to differentiate between pregnancy and ovulation.|||I am 6 weeks pregnant and had it about 10 days after sex. I think that after you ovulate your body produces the cervical mucus...and if you are pregnant and implantation took place...which is anywhere from 8-12 days post ovulation... your body just keeps on producing it. I had sex the day I ovulated....hope this helps...|||i have 2 kids im 25 it changes some times my 1st born was 10 days about and my second was about 12
