What Precautions Should Be Taken After Rupture Of Condom During Intercourse?

I have been having regular sex w/ my partner now. Im a girl, and while wearing the condom during sex, he said it broke. We stopped right away. He had not ejaculated. I am very nervous about what has happened. I am always careful and this is the 1st time this has happened. What should I do or what pre cautions should I take?
