I missed my period in November 2012. Then I only spotted light pink blood that I only saw when I wiped myself in Dec. The spotting lasted a week or so. I took a pregnancy test a week after the spotting and it was negative. Then I waited another week and took another one which was today and it was also negative. My question is... is it possible that I'm pregnant? Did I test to early or am I just having an abnormal situation?

Assuming you have engaged in sexual intercourse, then yes always a possibility.

Doing pregnancy test first thing in the morning as soon as you wake up?
