What to expect at 36 week apt?

I go for my 36 week apt tomorrow. For some reason i'm very nervous about it lol. I guess just bc it's getting closer to my due date. My doctor told me at 14 weeks that I may have to have a c section because my cervix was back so far and the way my uterus was shaped. I am getting the strep B test tomorrow so I will be getting my first exam since 14 weeks. So she should be able to tell me tomorrow if she feels ill be able to deliver vaginally or not right? Is the strep test like getting a pap test done? If not does it hurt or anything? And could I safely have my baby any time now?
