Does Pink Vaginal Discharge And Sore Breast Indicate Pregnancy?

I had my tubes tied in 2008 my first pregnancy ( which ended I miscarriage) was concieved on a condom my youngest son was concieved on the pill ( same guy both times) my period was a week early wasnt really light but it was a med pink to red my breasts were sore but not anymore and I did have bowel movement problems. Could I be pregnant or am I just imagining things? Now I hear my stomach making gurgling noises. Please help
