I had an internal ultrasound scan last week (roughly 7 weeks) that showed one gestational sac and 2 yolk sacs but no embryos. The sonographer said if she hadn't known my dates she would have thought I was just early on but with my dates she would expect to see embryos. Have a scan booked for 5th August to double check but we're assuming it's not going to be good news. Has anyone had a similar experience and had good news?
