Placenta previa? Any experiences?

So my doctor hasnt told me that im high risk but i have a slight complication, my placenta is laying really low and completly covering the opening of my cervix, at my last appnt which was at 19 weeks, my doctor told me this, she said further along in pregnancy it usually moves up, but as of now its covering my cervix, and if it doesn’t move away then there will be no way i can deliver my baby natrually, thankfully im not having any complications, im just kinda worried bc ima have to have a c-section if it doesn’t move, this is my first pregnancy...
