So I went to an appointment today because of some light bleeding and cramping and had my first intrauterine ultrasound of the pregnancy. This with a different doctor than the one we had visited previously. I'm supposed to be 7 weeks along but the doctor said the fetus was too small so she gave it 4 weeks which is impossible...she also told me that I was having twins but one didn't make it and got absorbed. .. she also didn't see a heart or hear a heartbeat. ..I don't know what to think. . We didn't see any of this with our last visit two weeks ago. Has this happened to anyone?
