Srry i just realized u ssid 4d not 3d ....oopps ...i never had that
I was told no later than 30 cuz they get too big
I say 30 weeks . But fair warning just because u get a 3d ultrasound doesnt mean you will nessacarily get to see baby smh i had one at 28 weeks and baby decided to play peek a boo & hide her face the entire time lol. But who knows ur baby may not be camera shy
Yeah that's a good week (: 27-32
