I started my period about nine days early and it was much lighter and shorter than normal.  Then about three days ago I started having really sore breasts, extreme fatigue, and a serious case of moodiness.  If I had not already tested I would swear I was pregnant! Is there anyway I could be pregnant and just tested too soon? 

You bet!  You could have implantation bleeding and just tested too early.  I would wait a couple of days (good luck with that ) and test again.  I always had a hard time waiting.  Patience is not something I'm really great at.  It sounds like you have all the classic symptoms.  Good luck! 

I know what you mean patience is not one of my virtues, either!

Waiting for me was really hard too. But after trying for so long I got kind of use to it. But it sounds like you have all the symptoms, i agree with the other ladies, you must have had implatation spotting. Try testing again in the next couple days! good luck!
