I have been ttc for about 5 months now. I had a period on November 5th 2012, and then some spotting on december 5th(or around that date), I was due for another period on January 2 2013 but i still havent gotten it yet. I have taken two home pregnancy test but they both came back negitive. I have noticed that i am eating alot more than usual, have been very moody at times and my pants are fitting a little tighter than normal. I have been having back pain and off and on headaches. I think that my stomach feels a little tight to (although i havent asked anyone else to feel.) My gums bleed just a little when ever i brush my teeth.
