My last period was on November 29th 2014 and ended on December 3rd 2014. I usually have pretty regular cycles so I always know around the time it is coming. For the past two days I have had very sore breasts, lower abdominal cramping, and a pink/light brownish color of something after I use the restroom. Could I be pregnant? I took a test today it came out negative, but is this because it is still way too early to tell whether I am or not?
