Hello, I would be happy to help you with your question.
It is not unusual to have an anterior low-lying placenta. This is not a placenta previa
. Given how early she is in the pregnancy
, I have no doubt that this will probably not be an issue in 12 weeks. In answer to your questions:
1. It is not currently dangerous assuming she is not experiencing bleeding. She needs to avoid intercourse or anything in the vagina and report any bleeding to her doctor
2. The placenta must be >2cm from the internal os at term to entertain a vaginal birth
3. If she is 2cm or less from the internal os at 38 weeks, then schedule a C/S at 39 weeks
