Anyone here ultrasound tech or know what I'm looking at?

[Pbn3]

Was wondering if anyone knows what I am looking at? Went for a scan today to rule out ectopic and locate tissue. U/S tech she couldn't say anything, but said she couldn't find anything but I found this on the pictures she gave me to take to doc. I'm 6w 1d but hcg has dropped again (back down to 38 from 51) so I know the pregnancy isn't viable/normal. But it says fetuses: 1 and the sac size is normal for my gestation but what's been measured in these pics looks like an empty space to me?? I have no idea and was hopeful someone may be able to shed some light. Thank you! I see my ob on Friday but just curious......https://uploads.tapatalk-cdn.com/20160113/68a211bd265ff6fabb9503f809af9df5.jpghttps://uploads.tapatalk-cdn.com/20160113/bdf42ab35318a05ba1ddbd1c94be137e.jpghttps://uploads.tapatalk-cdn.com/20160113/5c05e917b4dc7a52aacf9d983fcc5b8c.jpg

Not really able to offer insight to the u/s pbn but glad you have your bloods and scan.

My guess would be the yoke sac. I'm sorry things are going pear shaped xx

Thank you covered. do you know if the sac continues to grow even though the pregnancy isn't viable?

I think it's what they call a blighted ovum. https://en.wikipedia.org/wiki/Anembryonic_gestation
