Hi belle,
I saw what looked like a little cupie doll.Big head and little stubs for arms and legs.Lots of squirming too. The sonographer should print out copies for you but just ask before he/she starts to make sure. I couldnt see a profile or anything like that but the shape was there. Also not sure about a disc or video, I didnt ask, but if you contact the surgery Im sure they will tell you if they can record the session for you.Also they can poke and prod you quite firmly and it may be a little uncomfortable esp with a full bladder, dont worry though bubs will be perfectly safe.
Its all pretty exciting, emotional, etc so goodluck and enjoy seeing your new bundle for the first time. You will never forget it
