Pregnant?

Okay my friend just turned 15 and she had sex with her boy toy or whatever he is and he came inside her, but they had a comdom and she's not sure if it broke. Is there anyway to tell if it broke? Would the girl be able to feel it? Is there any way you can reduce the risk without using birth control or the after pill, she's not old enough to get it and her friends can't do it for her. Please respond soon. This was about an hour ago for her.
