My lmp was September 11th. I ovulated on September 25th. My hcg levels were taken on October 13th, at 139, then October 18th on 864, the again on November 9th at over 11,000. I had an ultrasound November 8th that had the baby at 6 weeks 3 days. I was told I would miscarry because a heartbeat couldn't be detected. I was told by a different doctor the next day, that the baby is just six weeks 3 days, and nothing bad since no cramping, no bleeding and good hcg levels.I am confused. Any advice/
