My mom says she wants to take me to the gynecologist to check my virginity. Is it possible that the doc will be able to tell whether i have lost it or not?

I used to be on BC, but when I found out I was taking it wrong I had to stop. I'm supposed to start it again the Thursday after I get my period... that is if my period comes. This is why I'm here. My boyfriend and I had unprotected sex, and I asked my mom if my period could be late because I'm no longer on BC. She became suspicious and a few days later we talked. I'm 17, by the way. She told me if I am pregnant that I'd have to abort it because I don't have the money or time to support a newborn, not to mention I'm starting college in August. She told me if I want to keep it then I can't live in her house. If I want to keep it, I have to PROVE to her that I am old enough to deal with it. So my question is directed towards abortion. How is an abortion performed, and does it hurt? I'm starting to get a little worried now because my period is late... and I can not (emotionally) handle a Pregnancy Test. I just can't. I told my boyfriend, who is 20, the situation. He's Mexican, and I am white. He freaked out because they're Catholic, and don't believe in abortion and they're all family oriented. He kinda got mad and was like, "you're going to kill my f------ baby." My mom told me he doesn't have a say in this whole situation, so I guess I have another question... how can I help him cope with this? Or is this something he just has to cope with himself? Thanks for reading, hope you can help! (I'm sure you can!!! :])
