What is considered viability in pregnancy?

Doctors often consider fetal viability the point at which a baby can be resuscitated at delivery and can survive without significant morbidity. Many times this age of viability is about 24 weeks gestation.

What week do you get your final ultrasound?

Fetal ultrasound is usually done during pregnancy to check the age, size, and position of your baby. Most of the time it is done at about 18 to 22 weeks. If you are sure of your last menstrual period and dont have any risk factors for birth defects, you probably dont need to have this test any earlier.

How early can you tell if a pregnancy is viable?

After 6 weeks, a normal fetal heart indicates a viable pregnancy. A fetal heart with no heartbeat at any point is called fetal demise. After 22-24 weeks, a viable pregnancy is when a baby has a chance to survive outside of the womb.
