There is definitely a chance that she could be pregnant. Pre-ejaculate (which is on your penis when you get aroused) can cause her to get pregnant. And pulling out alone can't always prevent her from getting pregnant.

I would advise you to take her to get the morning after pill as soon as possible. And next time, play it safe. Use a condom. If you're going to be having regular sex with her, look in to other forms of contraception. The pill (for her, and others similar) are great ways of preventing pregnancy. That, with the use of a condom, will lessen the chance again. And the condom will prevent the spread of any STI's.

It's better to be safe than sorry. You're clearly worried about getting her pregnant so you should use contraception then you need not worry. It's both your responsibilities to use contraception, as it will be both your responsibilities to raise the possible child.

Stay safe.
