They ask you if you smoke, or if your family has any history of things like stroke or heart disease...I think that's about it. From my experience, the docs have never asked too many questions. If you have any particular concerns that BC could address, such as acne, bad cramping, heavy bleeding make sure you mention that to ur doc. She could prescribe you one specifically for your needs. Be sure to tell her things like that though, because they don't tend to ask specifics (other than the health risks like strokes).

Also, most pills come with a huge list of side-effects but most of them say those effects should be gone within the first 2 months of using the BC. Definitely don't be afraid to go back to the doctor within that time, if something is really bothering you. I got severe mood swings to the point of being depressed often for no reason, that i only used that specific pill for only one month. I also tried the patch, but I didn't feel it was adhering to me as it should, so I went back to the doc 4 days later cause I was freaked that it wasn't protecting me.

Last thing, have you brought up sex-related stuff with your doctor before? I don't know where you are in the states, but doctors in many areas have to right to refuse to write you a prescription for BC if they feel like it's "immoral" in their eyes. In other words, if you are a single female they might feel it is "wrong" for you to be having sex, and therefore refuse your prescription. Also, pharmacists can refuse to fill your prescription on moral grounds as well. If this happens to you (im not saying it will, it's just something to keep in mind) go to a Planned Parenthood clinic. They can get you birth control for free I believe.
