Is this illegal?

So I have a friend that I am concerned for. She is 17 and is dating a 14 year old boy. She came up to me the other day and said that she might be pregnant. It's too soon to tell. She said they just did it once and it only lasted a minute because he couldn't get it in far. Sorry if that's too detailed. So I was just wondering what the consequences might be for her if she were to get pregnant. Would she go to jail with a baby??
