Which ultrasound is better?!?!

Jasmine

So I’m 29 weeks pregnant with my first! Baby boy! 💙 & doctor said if I’m going to be getting a 3D ultrasound to get it down now-32 weeks or it starts getting cramped in the womb and pictures won’t be as good....so I wanted to get that ultrasound done but i don’t know which is better 3D 4D or HD live ultrasounds. any moms out there who’s had 3D/4D/HD Live ultrasounds let me know!!! I wanted to get HD live but i don’t know if it is better or just getting the 3D ultrasound is fine.
