Yesterday in my midwifery course we watched a film on ultrasound safety and use. Basically, the FDA did studies and found that women who have 3 or more ultrasounds during their pregnancy are at risk for low birth weights. They also had all these images of how ultrasound makes cells look really strange & almost cancerous. Suffice to say, it was kind of scary.
Anyway, I just want to suggest that y'all look into ultrasound safety and are informed when you get them. Clearly there can be benefits to getting them, but they really don't need to do them every time a woman goes into the doctors office. Mostly that is just for their records and serves no purpose.
