Dealing with a mean and disrespectful OB/GYN

My OB, who I didn't even choose because she was the only one in my town with an opening, has been extremely rude and disrespectful to me at every appointment. On my first visit she kept asking me if I was going to keep it and every time I said yes she looks at me and makes this "are you kidding me" face. She basically man handled me during my exam bad enough to make me bleed for a day after my pap. On my second visit she asked why I was being so careless and irresponsible to allow myself (and I quote) to get "Knocked up so young". It's not like I planned this but what if I did? And it's not like I'm bringing an unwanted child into this world. It was just unexpected. To top things off she constantly asks how my husband (24) and I(21) being so young and irresponsible are going to afford this. My husband and I are both in the military. We have a solid paycheck, a house given to us if we choose and if not we get housing allowance, daycare provided at low cost, full medical benefits for us and the child. All this she knows and she is still rude towards us. I have no choice but to stay with her since there is no other options at this time but I wanted this to be a happy joyful time and she is ruining it for my husband and I. I've talked to her about it but she just shrugs and walks out of the room before I can finish. It is coming to the point where I want to put off my appointments just so I don't have to see her. What do I do to deal with this woman?
