How long after conception do symptoms of pregnancy begin to occur i may have conceived 6 days ago and am experiencing milky white discharge feeling hot often and increased sensitivity down there?

Pregnancy symptoms do not usually appear until about 10 days after conception as there is not sufficient hormone to cause symptoms until then.

None of the symptoms you have described are pregnancy symptoms, it sounds more as though you have an infection. You may of course be pregnant as well.

See a doctor to check for infection and if your period doesn't arrive do a pregnancy test.
