Hi everyone! Looking for opinions regarding the scan photos posted below. Had the scan a week ago, it’s my 3rd baby, measuring 7w exactly. Saw a heartbeat and all is well. But, I have been extremely worse off morning sickness wise during this pregnancy then my previous two (both girls), and a few close friends have suggested it could be due to twins! Anyway, looking through a video generated during the scan, it looks as though there are two sacks? I didn’t notice it whilst having the scan or I’d have asked my sonographer. I’m assuming it is something unrelated to the pregnancy as sonographer didn’t mention it at all during scan, but very curious to learn what it is! Does anyone know what I’m looking at? Could it be twins or something else? Thanks! For reference, in the first two photos the ‘sack’ that baby is in is on the right.
