I had mid cycle spotting around the 1st of this month. Around that time I was also experiencing sore breasts. At this time I was housing sitting- new responsibilities, new wake up time,etc. My period was due on the 12th, and has yet to come. I took a home pregnancy test on the 7th that was negative. For the past week and a half I have began exercising more frequently, running up to two miles a day. My breasts are no longer sore but I don t have much of an appetite, and I feel bloated and gassy most of the time. Could I be pregnant?
