According to my LMP I should be 8 weeks today. But I just came back from the drs and he said baby is measuring 6 weeks and we couldn't hear a heart beat. He kept asking if I was certain I didn't have my LMP later, but I am positive of the day I started. Has this happened to anyone else??? I'm freaking out because my last pregnancy ended in a miscarriage, and I don't think I can handle going through another one 😢
