Shoulder dystocia

Anyone have a previous shoulder dystocia come up during birth? I am three weeks away from having my next one and because of my history of this my dr is strongly urging a csection this time... my previous two were vaginal deliveries so I am nervous about a csection. This time I have developed gestational diabetes unfortunately but we have closely been monitoring his growth and although he is on the bigger side my specialist says she doesn’t see why I can’t try for vaginal but my ob is really pushing the csection so I am torn... anyone else go through this and not have issues with subsequent births vaginally?
