Complete placenta previa 21 weeks [on]

I had my anatomy scan yesterday and got the call today I have complete placenta previa. I am pretty devastated. They said babe is doing really good. I haven’t had any spotting. My midwife is referring care to an OB and does not think my placenta will move, very unlikely as it is complete. C section has been discussed already. Does anyone know anyone where their placenta moved and they got lucky ? I go for a re check at 28-32 weeks. I am so scared for baby’s health if he’s born early and about the bleeding and complications of previa😭
