I'm 9 wks with Di/Di twins. A and B are both measuring right on dates with their CRL but their sacs are measuring more than a week behind. I was wondering if anyone else had dealt with this. My doctor doesn't seem concerned, then again nothing really gets them excited. I of course think this is some bad sign, but maybe it's just because they have to share space? Any stories would be appreciated!
