Getting on birth control..

The other day I went to the doctor to get back on birth control. I told her I was interested in the pill or the implant but wanted more information on them. She lightly went over what I asked for and then in depth gave me information about Skyla, which I don't want. In the end I got back on the pill. 
My question is, when you get put on birth control, the doctor should perform some sort of pregnancy test, correct? Because my doctor did not and it just seemed off to me.
