Clear/white cervical discharge?

I am now 6 days late and I have clearish whitish discharge. Does this happen after conception? it would be less than a week if so, I am kinda freaking out because I already have a baby and don't want to get pregnant again for another year atleast. My periods are always like clockwork and I always get cramps just before so I know its coming, I haven't had any of the normal signs! I can't get a test for another few days so Im just wondering if this is a sign or am I panicking over nothing? I havent been under any stress or change in diet or anything that might affect it, me and hubby used a condom too :-/
