I just came back from my dating scan. I am 5.2w and we sac our little.gummy bear then the tech start making some funny sounds and ask if I have bad morning sickness .... she laughed and said that she could see two sacs but one is weirdly shaped and we can'tsee nothing in there for the moment cause it can just be too small . It might not even be a twin at all but shee couldnt tell and she let me see a climps for 3 seconds but i didn't realy see the difference between the 2 sacs du to my bladder beeing soooo full !! So for the one of you who had a transvaginal ultrasound at 5 weeks ... were your 2 sacs the same kind of shape ? You think i'll see a second baby in there when i'll go back in 3 weeks ?!
