Your profile shows you are a male...and if you had your last period on the 29th of November there is no way you would have the symptoms you are mentioning untill at least another two weeks. I should know I have been pregnant 5 times!
If you are female, for goodness sake, get some birth control happening, woman!
You mentioned the 29th, what is the significance of this date? That would be tomarrow. When did you last have your period and when in correlation to that date did you take the pregnancy test? All of your symptoms sound IDENTICAL to what I experienced and I am 16 weeks pregnant. You may want to go to the doctor and get a test done or try again with a home test if you prefer, but if you took the test before a missed period it is too soon to be accurate, so keep your fingers crossed. Or maybe not being as you are using the unprotected sex pull out method WHILE indulging in lots and lots and lots of sex with a guy you haven't even been dating for 6 months, it sounds as though you want to become pregnant. It sounds like your chances are good so congrats!
