Csection, water broke..

Ok ladies so most likely I’ll end up having a csection because my big 7 pound 5oz baby is still breeched. I’ll be 36 weeks thur...My doc is hoping he will turn and so am I. She said probably at this stage he might not turn because he is so big i guess we’ll see. They are also monitoring me closer because I have been getting a lot more swollen, docs monitoring me for preeclampsia also. So my question is after the long intro I gave is has any moms who had a planned csection water brake sooner? If so what happens? Doc said i will most likely have mine at 39 weeks..which I feel like this guys may come sooner🤷🏻‍♀️
