My teen age daughter is pregnant? Devastated?

My teenage daughter Leela is pregnant. She is only 15 years old and she told me this morning. She said it happened with a boy named Rynell but they are not dating, they just slept together a few times. I am very upset. She is going to keep it. She wants to raise it. I told her OK it is her decision. She is excited now. I told her it will be hard. She wants to name the baby either Rynell Jafarell Jr. or Mystique Rainna. I said NO, that kid will never get a job. If you name it that. I said she has 4 choices of names: Henry, Martha, Bill, or Jane. She said NO but I said it is my money. The baby is due in December. I want it to be a Christmas baby (Dec. 25) and she has no choice.
