I've been to the hospital about 3 times in the last month because I feel pregnant. I cannot even brush my teeth without throwing up in the morning. I have constipation and when I do go its always loose or diarrhea. I have lower abdominal pain in my right side and I also go to the bathroom frequently. Yesterday, there was some sticky white discharge coming out of my right breast. I just feel pregnant, I know my body. But, all the hpts, urine and blood tests done at the hospital have all been negative. Am I pregnant? And if not, what else could cause all of these symptoms.
