Just wondering if anyone knows much about them and what I could expect to see? I'm 32+2 and DH were thinking of going for one at the weekend. Is that a good time for one or should we wait a few weeks? We already know the gender, and it'd be lovely to see baby again and check everything is ok, but I'm not sure if I'd want to see my baby's face before the birth. Is that weird? Also is there much difference between 3 and 4d? Thanks
