Placenta previa and sonographer

So I have a stubborn marginal placenta previa and had a follow up ultrasound last week at 32w. My obgyn has 2 sonographers but I predominantly have only ever seen one in particular and she is fantastic. Well last week I saw the other lady and as time goes on and I've thought ab the incident it has upset me more. She informed me that placentas do not move after 32weeks and I would have to have a scheduled csection which really upset me. I know it's a strong likelihood but having her say theres no other choice now was def disappointing. My dr didnt mention this just said we would check again in a few weeks. But I was still sad based on what the sonographer said. So I start doing research and a large portion of placentas move after 32w. So she lied to me. Whether intentional or unintentional idk. It def has frustrated me and I will be requesting to not ever use that tech again.
