Generally we would suggest doing the 4D scan slightly later at around 30-32 weeks gestation if you have a high BMI.
Can you have a 4D scan after 30 weeks?
So, to answer your question: the best time to have a 4D baby scan is around 27 weeks. However, this does not mean that a satisfactory image cannot be captured later on; every pregnancy is different, of course, but we are almost always able to achieve great results up to 32 weeks.
How late can you have a 4D scan?
If you decide to have one, the best time to have a 3D or 4D scan is when you're between 27 weeks and 32 weeks pregnant. Before 27 weeks your baby has very little fat under her skin, so the bones of her face will show through.
Can you get 3D 4D ultrasound after 32 weeks?
After 32 weeks, your baby's head may go deep down in your pelvis, so you may not be able to see her face. Are 3D scans safe? If you're pregnant with twins or more, it's best to have a 3D or 4D scan earlier rather than later, when you're about 27 weeks pregnant, so you can get a clearer view of each baby.
How late can you have 4D scan?
How far along should I be before I have a 4D ultrasound? If you plan on having only one 4D ultrasound session, we would recommend having the ultrasound performed between the 26th and 34th week of the pregnancy. However, excellent images of your baby can be obtained anytime after about 22 weeks of pregnancy.
Can you have a 4D scan at 36 weeks?
3D & 5D ultrasound images and 4D ultrasound video can be obtained at any stage. However, we do recommend a gestational age of 26-34 weeks for the best facial detail.
