I had very light, brown spotting when I was due for my period on June 2 (I'm pretty regular and my cycle is about 30 days). It was very light and lasted 4 days on and off. I took a HPT when the spotting stopped and got a negative result. I had some abdominal discomfort and saw my Dr. a couple of days later and she did and urine pregnancy test in her office that came back negative also. But now it's June 14th and I have extremely tender breasts and they feel heavy and sore. Is there a chance or is it likely I could be pregnant?
