I am so confused!!

I feel pregnant! Consistent nausea, like queasy, I have lost nine pounds in 9 weeks. I took a pt when my cycle was starting (at thanksgiving) after ovulation, negative. My cycle was not normal and it was two days early. So I took another at the end of that week, still negative. I decided to wait until my next cycle. It was "on time" but again not normal (now at six weeks po). Both this cycle and the last produced no "normal" symptoms either, so I found myself taking the third pt on the day I was to start, negative. I decided my female parts have gone on strike! But I still have no appetite and still queasy and my cervix hasn't dropped down for nine weeks since the menstrual cycle before the last time I had sex.
