Aww lil miss you wont be abke to get a good pic if you go now cos i was told 32 weeks is the limit, just becasue youl go and exoect a great picture and it wont be at all because of the reduced amniotic fluid.
4d scans are fab peachy! Why not google for one where you live? There expensive over here, but not sdure what they would cost where you are.
