Can she get pregnant from me rubbing her vagina?

My girfriend and I where "messing around" and I was fingering her butt because her vagina is really tight and her cherry isn't popped. So anyway she was stroking me and I was fingering her. Then I touched myself with my other hand. And I think I had some pre*** .but I was rubbing her with the hand Itouched myself with. I was rubbing near her clit and a little lower. Because I can finger her because it hurts her cause it's so tight. But I was fingering her in the butt and rubbing her with my other hand.And she told me to stop so I did and she went to the bathroom and came back and said she bled a little and she was curled up and was in pain. I'm afraid I tried to go in and hurt her somehow. And could she be pregnant? (she is on birth control) 

Im just really worried that she is pregnant. She doesn't think so but I'm just really cautious.... Please help me out here! (I never ejaculated) I'm REALLY SCARED!
