Ok, Im having cramps here and there, no period, first day of my last period was Decemeber 31, 2012. I ve never missed a period and i also have sore breast(basically all the signs of pregnancy), I m 6 days late. I dont use the restroom a lot but more than i have in the past, i also have constipation , pains in my stomach , moodswings(angry, sad etc.) does this mean i could be pregnant?
