Can placenta previa be diagnosed by abdominal ultrasound at 12 weeks of gestation? and how accurate the diagnosis will be?

Likely to resolve: It is most common for this to resolve as the uterus grows during pregnancy. The position of the placenta tends to move up and away from the cervix as the uterus grows. Congratulations on your pregnancy!

Yes.: The location of the placenta can be identified at 12 weeks. If it covers or overlaps with the cervix, it's called placenta previa. However, the placenta can migrate during the course of pregnancy, so repeat ultrasounds are recommended as the pregnancy progresses.
