OBGYN or planned parenthood??

I told my boyfriend that I was going to go to planned parenthood instead of an OBGYN. Reason because I really just want to get checked make sure everything is good down there and get the pill. He says an OBGYN can help too but the thing is I'm doing this behind my mom's back. She thinks I'm still a virgin and is very strict and thinks planned parenthood is just abortions. Everytime I mention an OBGYN to her she flips out about me having sex and how I cant until Im married and my boyfriend thinks planned parenthood people aren't real doctors. So I just need your opinions on the situation.

Thank you!!
