Is my Gf really a virgin? or is she playing me?

My future Gf asked me what I would think if she told me she was pregnant??? does that mean she is pregnant or is she just wondering,we've been going out for a while but never had sex yet, I asked her and she says noooooo I dont plan on getting pregnat anytime soon. So what do you think? and we are both only 17 yrs old and she is almost 18 next moneth and I dont turn 18 until april . We havnt met in person yet but we do intend on meeting soon, we have already got evrything planned out. Also I asked about when we do have sex if she would like it anal and she said it would seem painful, and I asked how ofen we would have sex and she said it depends on if she is in the mood,
