Anterior Placenta Previa at 22 weeks?

Hi I had an ultrasound yesterday and it showed that I have a partial anterior placenta previa. They made me an appointment for today and the doctor sat with me and told me that I needed to take it easy. No , No lifting, No work, No exercise resting as much as possible. I am 22 weeks and 4 days and he told me at 28 weeks they will do another ultrasound because it may move. But if not then I will have to have a c-section at 36 weeks (I was having a c-section anyways, because I had one with my first child), but I was told that because mine placenta is anterior they will have to cut through it to deliver the baby. And that can cause increase risk of bleeding and lead to a blood transfusion or hysterectomy. Has anyone ever went through this? Does anyone know how many c-sections with a anterior placenta previa end in hysterectomy and blood transfusions? I am so scared!
