Doctor "Doesn't Do Birth Plans"?!

Hello ladies!
So I asked my doctor at my last visit about filling out a birth plan, and was surprised by her response. She said that they don't do birth plans, and that labor and delivery doesn't always go as the patient would like, and she doesn't want any unrealistic expectations. I was shocked and kind of just said "ok" and moved on. Well, now I'm wondering at what point and who do I tell my wishes? For example: delayed cord clamping, skin to skin, etc. 
I'm a FTM so I don't have any experience with this. Anyone have insight? 
Thank you!
