Am I pregnant or just PMS-ing really bad?

I went of my birth control the beginning of October had my cycle on the 10th of October, then my next cycle started on Nov. 14th. My husband and I were VERY active starting around 11/18 through the beginning of December. My cycle is due on the 19th if I go by the 35 days like last month. I am having super sensitive , they have changed a little, more perky or THO I guess you call it, they are like that all the time. I have had some nausea spells, and a few dizzy times. My bm's have changed as in I am not going as frequently as I used to but I am urinating more. I'm not sure what to think we really want to get pregnant. I took a pregnancy test on Dec 8th and it was negative. So I don't know, I'm really impatient and wanting to know really bad. We're going through a hard time in life and it would just brighten everyones day (my family)....any advice?
