Pregnancy Info HOME

I went to dr. yesterday and everything went great. Urine was clear, cervix and uterus looked great. Thought I was 7w4d. Done u/s and dr. said i was only measuring 6w0d. Had gest. sac and fetal pole, but no heartbeat. He also told me that I had a lot of blood around embro that "could" be implantation blood, but he didn't think there would be that much. Go back in 7 days for another u/s to see if any growth or heartbeat. Has anyone ever experienced this? I've had 2 previous miscarriages so I'm so scared. Please let me know. Misty
