Hoping/praying for a miracle, not a miscarriage

KMH
Hello all. November 23rd was my 43rd birthday. We have been TTC for baby #2 for 3 years (we have a 7 yo). I had a miscarriage in February 2016 at 6 1/2 weeks after 2 days of spotting and then bleeding. Now, I am pregnant again!LMP was 9/27/2016.Positive HPT was 10/24/2016!!Pregnancy confirmed at doctor's office on 11/8/2016.First ultrasound on 11/17/2016 (7 weeks, 2 days). Only gestational sac was seen, measuring 13 mm (5 1/2 weeks). No fetal pole, no yolk sac. "We are not seeing what we want to see at 7 weeks."Doctor scheduled another ultrasound for 11/28/2016 to "confirm the miscarriage." She is not offering much hope.I am very worried, of course. I don't have many symptoms at all. Lack of appetite, but no nausea. Easily winded, some burping... but I mostly feel pretty normal. I think I have been told in the past that I have a tilted uterus, but I'm not sure. I prefer to spend these days waiting in hope instead of despair. This site has allowed me to do that. If the worst comes to pass, it will be devastating regardless... so why not hope?
