"Harris bright fetal medicine unit"

I decided to take part in there fetal research programme which I found most of the time the staff were very nice. I had all together around 5 scans, at my 4th scan I was pleasantly surprised that I would get a 3D scan but was not able to get one due to babys hands in the face so was told that I would get some nice pictures at me last scan. At my last scan appointment while I was getting my blood drawn, I was told again that I would get nice 3d pictures but once in the scan room it seem as though the sonographer was not in the mood to give me pictures, I asked them and they told me to take a picture of the side profile of my baby. I am really annoyed because i was really looking forward to the 3D images and it seem as though they are happy for me to travel all the way from Kent to get what they wanted but were not willing to go out of their way in return. If I was asked to take part again I would refuse and would also remind others to do the same.
