Hello, I Am A Fifteen Year Old Girl And I

Hello, I am a fifteen year old girl and I was wondering if fingering could lead to pregnancy? I've researched through some websites and most say its slim to none and it's only possible if he had any sperm on his hand. I'm not quite sure if he did. I feel a little changed from that night which was only yesterday and my symptoms include some pain and discomfort in my lower abdominal region. Is this because he fingered me too much or too hard? Because I read somewhere that your cervix is very sensitive and your vaginal walls could be easily damaged. Please help, I'm rather scared of the possible consequences.
