Unprotected sex and symptoms!

My boyfriend and I had unprotected sex, until he was about to finish...then he put a condom on. Could I be pregnant?? I was supposed to start my period 4 days ago and I havent. I am usually very regular. I have some symptoms of pregnancy, but I'm not sure. I have felt sick to my stomach..not always throwing up but just a sick feeling. I have had to urinate quite often and it is a little cloudy. I also have a crampish feeling in my lower stomach, but I do not have tender breasts. Can I have some of these symptoms and be pregnant, or do I have to have them all? Also, I have been very moody? PLEASE HELP...could I be pregnant?

I'm replying to myself...Please is there any one out there that can help me?? I desperately need some advice ASAP!! I'm really starting to freak out...and now I have an excessive amount of vaginal discharge! What is going on?? PLEASE REPLY AND HELP ME!
