Over here you can get them done anything up for 40 weeks! :)
They recommend between 25-33 weeks for the best image. I had to reschedule mine bc it would have been too late
I had mine at 32 weeks and 34 week and I'm getting my last one done at 36 weeks I can't wait to see who he looks like more
I think they are better the later in pregnancy you are, more detail of baby :)
Nope I'm getting one at 32 weeks then another one at 36 weeks((:
