OB/GYN?????

Ok I'm 17 years old and my parents have never once talked to me about sex or even taken me to a gynecologist or whatever. Ever. I feel like I should've gone already just to know what's up down there. I resent my parents for it and I just feel uncomfortable. I'm moving out soon but I still wanna go get checked out first... HELP!! How do I do that? And how do I ask my mom to take me? I'm not comfortable with her at all but I need to go.
