Hello I hope someone can help me. 4 years ago I had a tubal ligation. I am currently 27 years old. During my last period it was cut short by about 3 days or so. I also have chronic hiccups, which I've had every other time I've been pregnant. I also have back pain and full cramping, nausea, mild headaches, food cravings that for me are strange, i am sensitive to smells not necessarily in a bad way, I feel bloated and it is all occurring a week and a half before my period should start. Is it possible I am pregnant?
