I thought I was pregnant at about 6 or 7 weeks. Went to a clinic. I had a negative urine test. They did a trans vaginal ultrasound to be sure & said they didn t see a sac or hear a heartbeat and assumed I miscarried. No blood test. Months went by. My stomach has been getting larger, but I thought I was just gaining weight (without changing diet). Didn t think much of it and have had semi-irregular periods since. The past week or two, I have felt movement in my stomach (mostly when I am trying to fall asleep) and my belly is hard above my belly button. I would be 25 weeks pregnant, if I was in fact pregnant. I was told when I was about 18 that they thought I had a heart-shaped uterus with a wall in the middle. I don t have health insurance. I feel really nervous and weird about going back to the clinic and asking for another ultrasound....and keep thinking maybe I am just imagining the movements I am feeling. Is it possible I am 6 months pregnant???
