Hi, I just went to my first prenatal visit yesterday. The first day of my last menstrual period was April 23rd. According to this date, I am 8 weeks and 3 days but I feel I may be earlier than that. My Dr saw an empty sac but oval shape, no baby. I am devastated. I haven t bled at all. She immediately sent me to a radiologist to take more ultrasounds and that dr found different results, a flatter sac. My dr was stunned because in less than an hour, my sac changed. What do you think? I am going for my next ultrasound on Monday to see if there is any progression. I feel pregnant and breast are sore. I am still having hope.
