More Ultrasound Confusion

So yesterday I had my first US at 5+2. (Based on my last menstrual cycle). The US technician was surprised I was there so early because she said they usually don't see anything till week 6+, but the scan saw a gestational sac but no yolk sac. I posted yesterday and a lot of you confirmed this was normal, so I felt a little better. Then today I got super conflicting info from my OBGYN. He sent the test results electronically and a message along with it that said "Your US results were normal and expected due date is July 4." But then I took time to read the results which were complete opposite. They said my gestational sac measured 6+1 vs the expected 5+2 days. And that my US was abnormal with an empty sac (no yolk sac) which means a non viable pregnancy. So I called my doctor and got the nurse who was also confused by the mix message and basically said she thinks the doctor made a mistake reading the results and they should order more blood work to see where my HCG levels are. And probably another US in two weeks. She said it's a 50/50 chance at this point. This was at 12:45 this afternoon that I talked to her. And still haven't heard back whether she got approval from my obgyn to get the blood work so IDK what's going on. But I know I am anxious and fearing the worst now. Already have been through a miscarriage and not ready to do it again. Thankful I at least have this place to vent my feelings and not bombard everyone in my life.
