Bleeding at 6 weeks 6 days

I went to the ER tonight because I was bleeding more than I have been since pregnancy. They scared me even though I just had an ultrasound on Tuesday. I waited in the ER for 6+ hours and it was torturous. Finally I got an ultrasound abdominal only and they said they could see the baby and heart rate of 116. They did a beta hCG which is my first one and it was 9922 but technically I should be 6 to 7 weeks and that number correlates with 5 to 6 weeks. It has me a little bit worried but I just have to have faith. Follow up ultrasound in two weeks.
