Has anyone????

OK ladies I know this sounds crazy but I am 27 weeks with my 5th baby but I go to a different doctor so you know all doctors are different. But I have had GB with all mine and with that be said my other doctor would just go head a put me on meds for it. Well this doctor he told me at my last appointment that my next appointment that I would be taken the one hour test. I told him I said I know I am going fail it well he never said anything. So next week I go but I look up his reviews and all people said is he is great at c section that they had to have one due to GD but I don't want a c section I have not had one with the other four and not now. I am so scared he going try give me a c section. And it has really hit me the last two weeks because my sister in law had her baby last week and he did a c section on her. I have try to change doctor but they all tell me I am to far along to change doctors. Has anyone of you had to have a c section because of GD?
