I had a period around October 15th laid about 5 days then again October 29th that lasted 2 days.. I had unprotected sex on my last menstrual and last time on November 3rd... Around November 5th I started getting milky discharge without smell or itching lower back pain, cramps that come and go, head aches, and frequent urination... sometimes feel nautious associated with light headedness... what could this be?

Don't know, but if you are pregnant, those symptoms are not due to it. It is too early for pregnancy symptoms to manifest themselves. The first true sign of pregnancy is missing a period.

Did you really just say those are not symptoms of pregnancy... sorry dear but I have had other pregnancies but never any symptoms until after missed period... if I go by the 1st period then I could be late if go by the 2nd period I should be starting no later en the 25th...

No, that's not what I said. While they may be symptoms commonly incurred during pregnancy, what I said was that it is too early for the symptoms to be indicative of pregnancy. As you admit yourself, you've never had these symptoms until after you missed your period. That is the first indication that a woman will have that she is pregnant. Anything else before that is due to another issue.
