A bit discouraged

So at 18w I was diagnosed with a marginal placenta previa. The drs assured me that it would move and not be an issue. Well today at 32w after my second follow up ultrasound it has not budged even a little bit. They feel like at this point it most likely will not move but will do another ultrasound at 36weeks to check again. If it has not moved at that point I will be scheduled for a csection. My first was born via csection my second was a vbac. I was really hoping for another vaginal birth. I know a csection in that situation is extremely important but I feel sad that I dont even have a decision about it. Yes I know baby and myself being healthy are most important but it's always tough when decisions are taken out of your hands
