its actually 26 weeks

They recommend from 28-32 anything over that they may not guarantee good pictures due to baby being to big & being smooched.

My specialist started doing 4d ones around 29 weeks and I continued until last week when I was 37 weeks which normally they can't get good images when they are that big but he doesn't want to drop down.

I'm getting mine this wk and I'm 33wks
