How do I know my pregnancy is viable?
Before 22-24 weeks, a non-viable pregnancy is when a baby delivered has no chance of survival, even if there is still a heartbeat in the uterus. After 22-24 weeks, a viable pregnancy is when a baby has a chance to survive outside of the womb.
Is monthly ultrasound bad for the baby?
All medical procedures have risk. But, there’s no evidence to show a prenatal ultrasound done properly will harm a mother or her unborn child. Done properly means it’s performed by a physician or a trained technician, called a sonographer. Ultrasound does not use radiation, as other procedures, such as X-rays, do.
How often should you get an ultrasound?
