Pregnancy Info HOME

So my LMP was 12/12/12. Was supposed to have my next one on 01/06/13. It never came. I started off with many pregnancy symptoms but now I'm down to just constipation, headaches, and really sore swollen breats. I've taken several hpts and they came back negative. Also got a blood test done and that came back negative. I have a dr appt next week on the 22nd and if my period doesn't come before my dr appt then I will ask my dr for another blood test an an ultrasound. Why have my symptoms gone from many to only a few?
