Just out of curiosity, for those that had placenta previa, at what point did you have the ultrasounds that determined you had it?
Not to downplay the seriousness of the condition, the most typical symptom of placenta previa is third trimester bleeding, at the point when small cervical changes are beginning to happen. Most women don't go that far into pregnancy without discovering it by ultrasound.
The placenta also sounds different than the baby's heart rate, or mom's heart rate, and it's often possible to get a general idea of the placenta's location. I'd imagine that if it's heard down low as the pregnancy progresses, that in itself might be an indication to take a peak with ultrasound.
